Technical Info
| Measurement under the microscope is a kind of non-contact measurement, that is, the measurement tool uses the points, lines, circles, angles, areas, three-dimensional of the image and the complex geometric images of the measured object to measure and calculate without contacting the specimen. For measurements, different optical systems and different measurement methods can be used, from the simplest measurement with scales to tools such as optical measurement platforms, as well as relevant measurement software etc. Measurement microscope is the general term for microscopes with this type of function. Non-contact measurement can measure the data of some small and irregular objects that are not accessible by conventional measuring tools. Especially after amplification of the microscope, its measurement accuracy can be very high, and the error caused by the optical system is small or even negligible. Basic Hardware Requirements of the Measuring Microscope: Lens Requirements: For microscopic measurement, it must be ensured that the image surface of the objective lens is flat. Optical microscopic measurement is actually to measure the image of an object. The image must overcome the curvature of field brought about by the objective lens and the image distortion caused by astigmatism so as to make the measurement more accurate. Therefore, for microscopic measurement, plan objective is recommended; for large-area long-distance measurement, the impact of perspective error also needs to overcome, for which, telecentric objective lens should be used. For microscopic measurement, single light path microscope is generally used, such as metallurgical microscope; for continuous magnification, video zoom lens should be used. Because the two optical paths of the dual light-path stereo microscope have an angle of 12 degrees, on each optical path there has actually a 6 degree inclination angle from the vertical angle, in such a case, the measurement will cause error. If the microscope is continuously zoomed, the main multiple points that need to be zoomed in should have magnification detent. Light Source Requirements: The light source for microscopic measurement should be uniform on the image plane of the field of view, and the bottom light should preferably use parallel light to make the outline and feature points clear. In theory, for microscopic measurement, it is best to use monochromatic light to reduce the effect of chromatic aberration, and therefore red light with the longest wavelength in the visible light is often used in measurement. Platform Requirements: Using optical measurement platform, it is possible to measure some large objects that exceed the microscope's field of view, and can achieve an accuracy of micron or even much smaller. The platform requires that the table plane should be of sound flatness, and maintains stable and leveling during movement. Moreover, the platform needs to have good rigidity, is not deformed or displaced itself, ensuring repeated measurement accuracy. Other Simple Measurement Methods: With the simple mechanism on the microscope, simple measurements and calculations can be performed on some observed objects that are not easy to use contact measurement. In addition to eyepiece reticle and objective micrometer measurement that we are familiar with, there are also other simple methods: for example, using the scale on the microscope stage, its accuracy can reach 0.1mm, which can measure the length of the measured object and roughly calculate its area; Using fine-tuning hand wheel mechanism of the microscope, calculate the height of the object to be observed by converting the fine-tuning number of revolutions into focusing stroke; using the rotating stage and the goniometer eyepiece, measure the angle etc. Calibration: Since the measurement is performed under the microscope on the image after the object is enlarged, it is therefore necessary to add a scale on the observed object so as to determine the actual size. The scale of a general microscope is called microscope micrometer, used to compare the actual size of the object or, as a scale6, to record to the measurement system. Generally, the reticle measurement on the eyepiece of the microscope is between 0.2 μm ~ 25 mm, of which 0.2 μm is the resolution of optical microscope, and 25 mm is the maximum diameter of the microscope field of view. The effect of the magnification should be subtracted from the measured dimensions. Or for the eyepiece reticle, it is necessary to coordinate with the objective micrometer to calibrate under the microscope, convert the grid value on the eyepiece reticle to the length on the objective micrometer, and then measure. In the XYZ measurement platform, the error caused by the measurement in the horizontal and vertical directions of the platform and the error caused in the repeated positioning accuracy by the rigidity of the platform should all be calibrated. For measuring microscopes and scales, the calibration of their system or measuring components is usually conducted by relevant agencies within a certain time frame to make the measurement more accurate. On the Error of Optical measurement: The reason for the error of measurement is multi-faceted. From the theoretical point of view, for rough measurement using eyepiece reticle to zoom in through the objective lens of the microscope, the influence of the error of system magnification is relatively large, and because of the geometric magnification error of the optical lens, the objective lens of ordinary microscope can achieve plus or minus 5%. Measuring with a scale on the objective lens, the problem of error of the measurement result caused by the magnification error of the objective lens can be theoretically solved. Measurement using mechanical platforms, regardless of the drive and measurement scale used, aside from the theoretical error caused by the depth of field of the objective lens, it mainly depends on the measurement reading mechanism, such as gratings, micrometers and dial gauges etc. However, the rigidity of the platform, the flatness of the platform surface, and the level of platform movement will still affect the measurement results. Therefore, finding the problem can improve effectively the accuracy requirements when using even a very economical equipment system. |
| Microscopes and components have two types of optical path design structures. One type is finite optical structural design, in which light passing through the objective lens is directed at the intermediate image plane (located in the front focal plane of the eyepiece) and converges at that point. The finite structure is an integrated design, with a compact structure, and it is a kind of economical microscope. Another type is infinite optical structural design, in which the light between the tube lens after passing the objective lens becomes "parallel light". Within this distance, various kinds of optical components necessary such as beam splitters or optical filters call be added, and at the same time, this kind of design has better imaging results. As the design is modular, it is also called modular microscope. The modular structure facilitates the addition of different imaging and lighting accessories in the middle of the system as required. The main components of infinite and finite, especially objective lens, are usually not interchangeable for use, and even if they can be imaged, the image quality will also have some defects. The separative two-objective lens structure of the dual-light path of stereo microscope (SZ/FS microscope) is also known as Greenough. Parallel optical microscope uses a parallel structure (PZ microscope), which is different from the separative two-object lens structure, and because its objective lens is one and the same, it is therefore also known as the CMO common main objective. |
| The magnification of the objective lens refers to the lateral magnification, it is the ratio of the image to the real size after the original image is magnified by the instrument. This multiple refers to the length or width of the magnified object. System optical magnification is the product of the eyepiece and the objective lens (objective lens zoom set) of the optical imaging part within the system. Optical magnification = eyepiece multiple X objective lens/objective lens set The maximum optical magnification of the microscope depends on the wavelength of the light to which the object is illuminated. The size of the object that can be observed must be greater than the wavelength of the light. Otherwise, the light cannot be reflected or transmitted, or recognized by the human eye. The shortest wavelength of ultraviolet light is 0.2 microns, so the resolution of the optical microscope in the visible range does not exceed 0.2 microns, or 200 nanometers. This size is converted to the magnification of the microscope, and it is the optical magnification of 2000X. Usually, the compound microscope can achieve 100X objective lens, the eyepiece is 20X, and the magnification can reach 2000X. If it is bigger, it will be called "invalid magnification", that is, the image is large, but the resolution is no longer increased, and no more details and information can be seen. |
| Total magnification is the magnification of the observed object finally obtained by the instrument. This magnification is often the product of the optical magnification and the electronic magnification. When it is only optically magnified, the total magnification will be the optical magnification. Total magnification = optical magnification X electronic magnification Total magnification = (objective X photo eyepiece) X (display size / camera sensor target ) |
| Field of View, is also called FOV. The field of view, or FOV, refers to the size of the object plane (i.e., the plane of the point of the observed object perpendicular to the optical axis), or of its conjugate plane (i.e., object to primary image distance), represented by a line value. System field of view is the size of the actual diameter of the image of the terminal display device of the instrument, such as the size of the image in the eyepiece or in the display. Field of view number refers to the diameter of the field diaphragm of the objective lens, or the diameter of the image plane formed by the field diaphragm. Field of view number of objective lens = field of view number of eyepiece / (objective magnification / mechanical tube length) Large field of view makes it easy to observe the full view and more range of the observed object, but the field of view (FOV) is inversely proportional to the magnification and inversely proportional to the resolution, that is, the larger the field of view, the smaller the magnification, and also the lower the resolution of the object to be observed. There are usually two ways to increase the field of view, one is to replace with an objective lens of a smaller multiple, or to replace with an eyepiece of a smaller multiple. |
| Working distance, also referred to as WD, is usually the vertical distance from the foremost surface end of the objective lens of the microscope to the surface of the observed object. When the working distance or WD is large, the space between the objective lens and the object to be observed is also large, which can facilitate operation and the use of corresponding lighting conditions. In general, system working distance is the working distance of the objective lens. When some other equipment, such as a light source etc., is used below the objective lens, the working distance (i.e., space) will become smaller. Working distance or WD is related to the design of the working distance of the objective lens. Generally speaking, the bigger the magnification of the objective lens, the smaller the working distance. Conversely, the smaller the magnification of the objective lens, the greater the working distance. When it is necessary to change the working distance requirement, it can be realized by changing the magnification of the objective lens. |
| For siedentopf eyetube, when changing the interpupillary distance, it requires two hands pushing or pulling the two eyetubes left and right simultaneously, and the two eyepiece tubes or eyetubes will change their position at the same time. |
| Usually the Microscope Eyetube is 45°, some is 30°, Tiltable Eyetube Angle design of a microscope is also known as the ergonomics microscope. 0-30° or 0-45° is an ergonomic design. When the mechanical tube length / focal length of the tube of the microscope is relatively big, the microscope is relatively high, and the user's height or the seat of the work desk is not suitable, long-term use of microscope may cause sitting discomfort. Eyepiece tube with variable angle can freely adjust the angle without lowering the head. Especially when it is close to 0 degree and the human eye is close to horizontal viewing, long-time or long-term use can avoid fatigue damage to the cervical vertebra. |
| After imaging through a set of objective lenses, the object observed and the image seen by the human eye is inverted. When the observed object is manipulated, move the specimen or object, the image will move in the opposite direction in the field of view. Most of the biological microscopes are reversed-phase designs. When needing to operate works with accurate direction, it is necessary to design it into a forward microscope. Generally stereo microscopes and metallurgical microscopes are all of erect image design. When observing through the camera and display, the erect and inverted image can be changed by the orientation of the camera. |
| The third eyepiece splitting in the trinocular microscope is to borrow one of the two sets of eyepiece optical paths as the photographic light path. The beam split prism or beam splitter can reflect part of the image light to the eyepiece, and part passes through to the third eyepiece photographic light path, such a trinocular microscope is called trinocular simultaneous imaging microscope, or true-trinocular. The beam split prism or beam splitter of the trinocular simultaneous imaging microscope or true-trinocular often has different splitting modes, such as 20/80 and 50/50, etc. Usually, the former is the luminous flux ratio of the eyepiece optical path, and the latter is the luminous flux ratio of the photographic optical path. The advantage of true-trinocular is that, the real three optical paths can be imaged at the same time, and are not affected by the simultaneous use of the eyepiece observation and the photographic optical path (display). The disadvantage is that, because of the reason of the splitting, the image light of the photography is only a part. In theory, the image effect will be affected, and the effect is more obvious in the binocular eyepiece observation. If viewed closely, one will find that the eyepiece of the light path is relatively dark. However, in the current optical design and materials, the impact on the actual work is not very big, especially in the observation of low magnification objective lens, it has basically no effect at all, and therefore used by many people. |
| The adjustable eyepiece is between the lens of the eyepiece and the focal plane, with distance adjustable device. For most people, their two eyes, the left and the right, have different vision. For adjustable eyepieces, the eyepoint height of the eyepiece can be adjusted to compensate for the difference in vision between the two eyes, making the image in the two eyes clear and consistent. The range of adjustment of the general eyepiece is that the diopter is plus or minus 5 degrees, and the maximum difference between the two eyepieces can reach 10 degrees. Before use, it is generally necessary to adjust both eyepieces to the initial position where the scale is displayed as 0, which is used as a baseline to facilitate up and down adjustment. The reticle position of the eyepiece is generally 10mm below the fixed position of the eyepiece tube. Because the vision of each person is different, some people may not be able to see the reticle clearly. For adjustable eyepiece, the height of the reticle position can be adjusted to make the reticle and the observed object clear at the same time, this is the advantage of adjustable eyepiece that mounts the diopter adjustment on the eyepiece tube compared with non-adjustable eyepiece. When non-adjustable eyepiece is equipped with a reticle, if the diopter is adjusted, the reticle will rotate accordingly, thereby affecting the position of the measurement. For adjustable eyepiece, when its diopter is adjusted, its reticle does not rotate. |
| Eyepiece optical magnification is the visual magnification of the virtual image after initial imaging through the eyepiece. When the human eye observes through the eyepiece, the ratio of the tangent of the angle of view of the image and the tangent of the angle of view of the human eye when viewing or observing the object directly at the reference viewing distance is usually calculated according to 250 mm/focal length of eyepiece. The standard configuration of a general microscope is a 10X eyepiece. Usually, the magnification of the eyepiece of compound microscope is 5X, 8X, 10X, 12.5X, 16X, 20X. As stereo microscope has a low total magnification, its eyepiece magnification generally does not use 5X, but can achieve 25X, 30X and other much bigger magnification. |
| The eyepiece field of view is the diameter of the field diaphragm of the eyepiece, or the diameter of the image plane of the field diaphragm imaged by the field diaphragm. The diameter of a large field of view can increase the viewing range, and see more detail in the field of view. However, if the field of view is too large, the spherical aberration and distortion around the eyepiece will increase, and the stray light around the field of view will affect the imaging effect. |
| Eye point refers to the axial distance between the upper end of the metal frame of the eyepiece and the exit of pupil. The exit of pupil distance of high eyepoint eyepiece is farther than that of the eye lens of the ordinary eyepiece. When this distance is greater than or equal to 18mm, it is a high eyepoint eyepiece. When observing, one does not need to be too close to the eyepiece lens, making it comfort to observe, and it can also be viewed with glasses. Generally, there is a glasses logo on the eyepiece, indicating that it is a high eyepoint eyepiece. |
| Eye guard installation refers to that the eye guard has been installed on the eyepiece in advance as a component. |
| The XYZ measurement stage has stage for measuring mechanisms in three directions, namely, the XY horizontal direction and the Z vertical direction. Generally, there is a relatively high accuracy in the XY direction, the accuracy of the Z axis is usually different from the XY direction in structure, and the accuracy requirements may also be different. In most of the structures of the XYZ stage, the manufacturing method and accuracy of the Z direction and the XY direction are the same. However, there are also measuring devices that use microscope focusing mechanism in the Z-axis direction to generate displacement by adjusting the distance between the stage or the microscope, and to measure the displacement distance in the displacement. The Z-axis measurement is consistent or similar to the measurement method in the XY horizontal direction, but differs in principle and measurement of error. In addition to the different accuracy errors caused by the possible differences in the XYZ mechanical structure, the error from the optical principle is more obvious. The Z-axis measurement has relatively more limiting factors, for example, some objects being measured lack obvious focus feature points, and cannot be measured. However, in some objects that cannot be placed in the XY horizontal direction, for example, the height of the soldered electronic components on the electronic circuit board, the depth of some tube holes, they are still a better method. Measurement method in the Z-axis direction 1. When making the Z-axis measurement, first use the intersection of the crosshairs to align the horizontal position of one measured starting point of the object to be measured, so that the microscope is focused to a clear image position. 2. Turn on the measurement scale 0 position, then find the plane position of the end point of the measured object, adjust the XY axis, move the intersection position of the crosshair to the said position, and focus up or down to find the clearest image position. In the above, it is also possible to determine the position of the starting point through the clear image of the measured starting point without adjusting the center point. 3. After reading the displacement before and after, the number of displacements occurring on the scale will be the height between the two points being measured. Measurement error in the Z-axis direction In the Z-axial direction, since absolute verticality cannot be guaranteed, when relative movement with the stage occurs, an angle of more than or less than 90 degrees will be generated with the stage in the tilted or oblique direction, and the more inclined the Z-axis direction, or the longer the movement, the greater the error. If the measurement error in the XY direction depends on the depth of field of the objective and the accumulated error value of the length of the object to be measured, then for the measurement error in the Z-axis direction, in addition to the vertical error in the Z-axis direction due to the Z-axis measurement, the measurement error value in the depth of field of the objective will be much bigger. In the Z-axis measurement, after focus of measurement, the positions of the start point and the end point may actually both result in error through the twice focusing of the depth of field, and the maximum range of the error can be twice of that of the depth of field. Because of the depth of field factor, if the object being measured cannot find the position of two different but clear focus points, it cannot be measured either. Moreover, it is also not possible to measure between two feature points smaller than the distance of the depth of field of the objective on the Z axis. |
| The movement of the general stage is along the direction of the guide rail, driven by screw or friction. The movement is more precise, but it is also very slow. In order to move the stage to a position quickly, a clutch-like switching device can be installed to make the movement out of the screw or the friction path so as to achieve the purpose of rapid movement. |
| The XY-axis measurement mode refers to the way the scale used when measuring the XY axis of the stage. For different system, the choice is also different according to the different accuracy and operation requirements, such as mechanical micrometer, capacitance digital display, encoder and so on. |
| XY-axis resolution refers to the minimum value of the measurement that the scale mechanism used can display when measuring the XY-axis. The resolution of the gauge refers to the scale value that can be read directly, also called the division value. For example, if the division value is 0.001 mm, that is, the resolution is 0.001 mm, and the numerical value of 0.001 mm can be read directly by the scale. |
| The XY-axis measurement accuracy refers to the actually obtained measured value when measuring the XY axis. The accurate measurement value can be guaranteed within the range of plus or minus of this accuracy value. For example, if the measurement accuracy is ±0.002mm, the measured value of the spare part read is X, then the true value range of the part will be Minimum size: X - 0.002 Maximum size: X + 0.002 |
