Technical Info
| Digital microscope is the general term for microscope that can convert an optical image into a digital image, and usually does not specifically refer to a certain type of microscope. It should be noted however that most microscopes can be mounted with cameras and display devices to change to digital microscope. Microscopes in the visible range, from the digital imaging point of view, all use CCD or CMOS sensors to image the optical signal as an electric signal on a computer or display. However, the difference between various kinds of digital microscopes mainly comes from the optical microscope itself, so it is necessary to look at the imaging effect and function of the optical part in order to select the type of digital microscope. From the classification point of view, digital microscopes can be divided into: digital biological microscopes, digital stereo microscopes, etc. It should be noted that due to the variety of lenses, ordinary lenses or microscopes, if mounted with a digital camera, can all become a digital microscope. At present, the trend of digital microscopes is not only to present simple digital images, but to collect, process and analyze images through back-end software, especially for image measurement, comparison, judgment, and large-format scanning and splicing, and three-dimensional synthesis and so on, these aspects have been widely developed and applied. |
| 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. |
| 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 ) |
| 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. |
| Zoom ratio is the ratio of the maximum magnification / the minimum magnification. Expressed as 1: (ratio of maximum magnification / minimum magnification). If the maximum magnification is 4.5X, the minimum magnification is 0.7X, then the zoom ratio = 4.5 / 0.7 = 6.4, the zoom ratio will be 1:6.4. Zoom ratio is obtained by the intermediate magnification group of the microscope. When the magnification is increased or decreased by using other objective lenses, the zoom ratio does not change accordingly. |
| The nosepiece of a microscope is generally switched manually. A motarized nosepiece is to add an electric motor onto the nosepiece to control switching of the nosepiece through the electric switch, so as to switch the objective used. This device can be added when some microscopes are bulky, switching of the objective needs to be kept steady, and needs to be frequently switched. |
| 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. |
| Electric/CNC platform refers to the movement mode operated and controlled by motor or digital signal during the XY or Z-axis focusing of the microscope and the movement of the platform. |
| The size of the CCD and CMOS image sensors is the size of the photosensitive device. The larger the area of the photosensitive device, the larger the CCD/CMOS area; the more photons are captured, the better the photographic performance; the higher the signal-to-noise ratio, the larger the photosensitive area, and the better the imaging effect. The size of the image sensor needs to match the size of the microscope's photographic eyepiece; otherwise, black borders or dark corners will appear within the field of view of observation. |
| The pixel is determined by the number of photosensitive elements on the photoelectric sensor of the camera, and one photosensitive element corresponds to one pixel. Therefore, the more photosensitive elements, the larger the number of pixels; the better the imaging quality of the camera, and the higher the corresponding cost. The pixel unit is one, for example, 1.3 million pixels means 1.3 million pixels points, expressed as 1.3MP (Megapixels). |
| Frame rate is the number of output of frames per second, FPS or Hertz for short. The number of frames per second (fps) or frame rate represents the number of times the graphics process is updated per second. Due to the physiological structure of the human eye, when the frame rate of the picture is higher than 16fps, it is considered to be coherent, and high frame rate can make the image frame more smooth and realistic. Some industrial inspection camera applications also require a much higher frame rate to meet certain specific needs. The higher the resolution of the camera, the lower the frame rate. Therefore, this should be taken into consideration during their selection. When needing to take static or still images, you often need a large resolution. When needing to operate under the microscope, or shooting dynamic images, frame rate should be first considered. In order to solve this problem, the general industrial camera design is to display the maximum frame rate and relatively smaller resolution when viewing; when shooting, the maximum resolution should be used; and some cameras need to set in advance different shooting resolutions when taking pictures, so as to achieve the best results. |
| Automatic focus function is the function that some cameras automatically focus within a certain range. These functions are only that the microscope provides autofocus within a certain depth of field, and as such, it cannot replace the microscope to achieve full automatic focus. Autofocus is very convenient and suitable to use when observing objects with a certain height at low magnification. After the microscope has adjusted a working distance, it is basically not necessary to adjust the focus of the microscope, especially when repeatedly testing the same sample, the efficiency at the time of detection can be greatly improved. |
| After unpacking, carefully inspect the various random accessories and parts in the package to avoid omissions. In order to save space and ensure safety of components, some components will be placed outside the inner packaging box, so be careful of their inspection. For special packaging, it is generally after opening the box, all packaging boxes, protective foam, plastic bags should be kept for a period of time. If there is a problem during the return period, you can return or exchange the original. After the return period (usually 10-30 days, according to the manufacturer’s Instruction of Terms of Service), these packaging boxes may be disposed of if there is no problem. |
