Technical Info
| Surgical microscope is a stereo microscope used for microsurgery, diagnostic treatment, observation, and research and other different functions of humans and animals under the microscope. An surgical microscope has an optical system for observation, including an eyepiece, an objective lens, an objective lens zoom set, and lighting, stands, and electrical components, and its accessories are configured according to different needs. The magnification of the surgical microscope is generally 8-20X. Compared with the stereo microscope, it has special requirements of large field of view, large depth of field, and long working distance, characterized by compact structure, small size and flexible operation. Surgical microscope typically has flexible, large-space moving stands and electric controls. For more precautions for use of surgical microscope, please refer to the Stereo Microscope on the BoliOptics website. |
| 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. |
| When the instrument is conducting electronic image magnification and observation through a camera or the like, the optically magnified portion may not be the optical path that passes through the "eyepiece-objective lens" of the instrument, at this time, the calculation method of the magnification is related to the third-party photo eyepiece passed. The trinocular optical magnification is equal to the multiplier product of objective lens (objective lens set) and the photo eyepiece Trinocular optical magnification = objective lens X photo eyepiece |
| 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. |
| The finite objective is the lateral magnification of the primary image formed by the objective at a prescribed distance. Infinite objective is the lateral magnification of the real image produced by the combination of the objective and the tube lens. Infinite objective magnification = tube lens focal length (mm) / objective focal length (mm) Lateral magnification of the image, that is, the ratio of the size of the image to the size of the object. The larger the magnification of the objective, the higher the resolution, the smaller the corresponding field of view, and the shorter the working distance. |
| In the case of polychromatic light imaging, the aberration caused by the light of different wavelengths becomes chromatic aberration. Achromatic aberration is to correct the axial chromatic aberration to the two line spectra (C line, F line); apochromatic aberration is to correct the three line spectra (C line, D line, F line). The objective is designed according to the achromaticity and the flatness of the field of view. It can be divided into the following categories. Achromatic objective: achromatic objective has corrected the chromatic aberration, spherical aberration, and comatic aberration. The chromatic portion of the achromatic objective has corrected only red and green, so when using achromatic objective, yellow-green filters are often used to reduce aberrations. The aberration of the achromatic objective in the center of the field of view is basically corrected, and as its structure is simple, the cost is low, it is commonly used in a microscope. Semi-plan achromatic objective: in addition to meeting the requirements of achromatic objective, the curvature of field and astigmatism of the objective should also be properly corrected. Plan achromatic objective: in addition to meeting the requirements of achromatic objectives, the curvature of field and astigmatism of the objective should also be well corrected. The plan objective provides a very good correction of the image plane curvature in the field of view of the objective, making the entire field of view smooth and easy to observe, especially in measurement it has achieved a more accurate effect. Plan semi-apochromatic objective: in addition to meeting the requirements of plan achromatic objective, it is necessary to well correct the secondary spectrum of the objective (the axial chromatic aberration of the C line and the F line). Plan apochromatic objective: in addition to meeting the requirements of plan achromatic objective, it is necessary to very well correct the tertiary spectrum of the objective (the axial chromatic aberration of the C line, the D line and the F line) and spherochromatic aberration. The apochromatic aberration has corrected the chromatic aberration in the range of red, green and purple (basically the entire visible light), and there is basically no limitation on the imaging effect of the light source. Generally, the apochromatic aberration is used in a high magnification objective. |
| The objective working distance is the vertical distance from the foremost surface end of the objective of the microscope to the object surface to be observed. Generally, the greater the magnification, the higher the resolution of the objective, and the smaller the working distance, the smaller the field of view. Conversely, the smaller the magnification, the lower the resolution of the objective, and the greater the working distance, and greater the field of view. High-magnification objectives (such as 80X and 100X objectives) have a very short working distance. Be very careful when focusing for observation. Generally, it is after the objective is in position, the axial limit protection is locked, then the objective is moved away from the direction of the observed object. The relatively greater working distance leaves a relatively large space between the objective and the object to be observed. It is suitable for under microscope operation, and it is also easier to use more illumination methods. The defect is that it may reduce the numerical aperture of the objective, thereby reducing the resolution. |
| For microscopes of different manufacturers and different models, the thread size of their objectives may also be different. In general, the objective threads are available in two standard sizes, allowing similar objectives between different manufacturers to be used interchangeably. One is the British system: RMS type objective thread: 4/5in X 1/36in, One is metric: M25 X 0.75mm thread. |
| 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. |
| Flexible arm is an arm or stand that imitates the human arm. It is a combination of several mechanical arm joints to complete the horizontal and vertical movement and freely adjust the focus position of the microscope. Flexible arm allows the microscope to move flexibly and freely over a wide range, and is also suitable for viewing larger objects. The fixing method of the arm is usually optional, with strong interchangeability. Below the observation of the microscope there is an empty workbench, which can be used to place various kinds of platforms, work operating tables, tools, etc., and can be freely combined into different working positions. In industrial places, most of the working positions are fixed. Sometimes, a lot of tools, equipment and instruments need to be placed in one working position. Because the microscope is relatively large in size and takes up also a relatively bigger space, and not convenient to move back and forth, therefore the flexible arm can be placed in a flexible position, and does not occupy the most commonly used workbench. When in use, the microscope can be moved over, and pushed to the side when not in use. This is very suitable for use in electronics factories, installation and maintenance, medical and animal anatomy, archaeology and other industries. Flexible arm generally does not have a fixed focusing device, and you can choose a variety of flexible accessories. When adjusting the height of the flexible arm, you need to use both hands at the same time, with one hand holding the microscope or the forearm of the stand, and the other adjusting the adjusting screw or spring mechanism that looses/tightens the arm. When releasing, pay attention to avoiding sudden sliding down. Because one needs to ensure the flexibility of the arm or stand, there are many locking buttons in all directions. After the necessary locking buttons are adjusted, it must be ensured that each knob is in locked state to avoid sliding, tilting, and flipping of the microscope, thereby damaging the microscope and the items on the workbench. Flexible arm has a mechanism of the hydraulic spring for adjusting the pre-tightening tension. When different microscopes weigh differently, these flexible arms can be adjusted to make the microscope more stable. |
| Base clamp is the clamp of the microscope stand that is clamped on the side of the desktop. Pay attention to confirm in advance whether the material and thickness of the tabletop can withstand the weight of the microscope stand and the body. |
| 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. |
