Digital MicroscopeClose ΛDigital 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.

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.

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.

System Working DistanceClose ΛWorking 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.

Track StandClose ΛThroughout the focusing range, the track stand moves up and down along the guide rail through the focusing mechanism to achieve the purpose of focusing the microscope. This kind of structure is relatively stable, and the microscope is always kept moving up and down vertically along a central axis. When the focus is adjusted, it is not easy to shake, and there is no free sliding phenomenon. It is a relatively common and safe and reliable accessory.

Stand Throat DepthClose ΛStand throat depth, also known as the throat depth, is an important parameter when selecting a microscope stand. When observing a relatively large object, a relatively large space is required, and a large throat depth can accommodate the object to move to the microscope observation center.

Inclination observation often has ergonomic requirements that allow the observer to adjust the angle at will, and using the microscope in a more comfortable position and sitting posture can help reduce fatigue.

In general, all inclination observations are to use microscope with low magnification, which requires a larger field of view and depth of field, otherwise the focusing will be more difficult.

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.

Video MicroscopeClose ΛVideo microscope, also known as TV microscope, is a microscope that converts an optical image into a video image. Typically, for video microscope, it is an analog camera that displays an image on a display or on a projection.

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.

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 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.

System Working DistanceClose ΛWorking 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.

The upper end of the microscope body can be connected to the standard C-interface photo eyepiece, and then connected to the microscope camera; the lower end is the objective lens, and the objective lens of parallel structure is generally separated from the body, whereas the microscope body of finite structure is combined with the objective lens.

Zoom RangeClose ΛZoom in zoom microscope means to obtain different magnifications by changing the focal length of the objective lens within a certain range through adjustment of some lens or lens set while not changing the position of the object plane (that is, the plane of the point of the observed object perpendicular to the optical axis) and the image plane (that is, the plane of the image imaging focus and perpendicular to the optical axis) of the microscope.

Zoom range refers to the range in which the magnification is from low to high. In the zoom range of the microscope, there is no need to adjust the microscope knob for focusing, and ensure that the image is always clear during the entire zoom process.

The larger the zoom range, the stronger the adaptability of the range for microscope observation, but the image effects at both ends of the low and high magnification should be taken into consideration, the larger the zoom range, the more difficult to design and manufacture, and the higher the cost will be.

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.

Magnification DetentClose ΛIn the body of zoom microscope, zooming is continuous. When rotating to a certain position, generally an integral multiple, a positioning structure or detent is added, which has a distinct hand feel during the zooming process, and stops at this position.

Objective Screw ThreadClose ΛFor microscopes of different manufacturers and different models, the thread size of their objectives may also be different.

The field of view number of the microscope 10X eyepiece is usually designed to be 18, 20, 22, 23mm, less than 1 inch (25.4mm). Since most commonly used camera sensor sizes are 1/3 and 1/2 inches, this makes the image field of view on the display always smaller than the field of view of the eyepiece for observation, and the visual perception becomes inconsistent when simultaneously viewed on both the eyepiece and the display. If it is changed to a 0.5X coupler/C-mount-adapter, the microscope image magnification is reduced by 1/2 and the field of view is doubled, then the image captured by the camera will be close to the range observed in the eyepiece.

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.

White balance of the camera is to "restore white objects to white color under any light source." The chromatic aberration phenomenon occurred under different light sources is compensated by enhancing the corresponding complementary color. Automatic white balance can generally be used, but under certain conditions if the hue is not ideal, options of other white balance may be selected.

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.

Objective Working DistanceClose ΛThe 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.

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.

It is a relatively large pole type stand. The height and length of the stand are big, and it can be freely adjusted in height, length and various angles. Its large weight ensures stable support and occupation of large space, but it can make the microscope free to move in a wide range with convenience. Boom stand is suitable for observing large objects.

The direction of boom stand is flexible, and when in use, various kinds of positions and methods can be adopted, such as front, side, and tilt etc., to facilitate the layout of the workbench. On the side of the crossbar of the boom stand, a 5/8-inch connecting hole is generally left for connecting various focusing mechanisms and microscopes.

The base of the boom stand usually only plays a fixing and supporting role. Under the observation of the microscope, it is an empty workbench, which can be used to place various platforms, work operating surfaces, and tools, etc., and can be freely combined into different working positions. When the base is large, the object to be observed can also be placed.

In industrial places, most of the working positions are fixed. Sometimes, in one working position, a lot of tools, equipment and instruments need to be placed.. 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 for purpose of use, the boom stand can be placed in an appropriate position, and does not need to occupy the most commonly used work tables. 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.

Because the stand needs to ensure flexibility, therefore there are many locking buttons in all directions. In any time after adjustment, it must be ensured that each knob is in a locked state to avoid sliding, tilting and flipping of the microscope, thereby damaging the microscope and the items on the workbench.

360° Degree RotatableClose ΛThe eyepiece of the microscope can have different viewing or observing directions. When the position of the microscope is uncomfortable, the direction of the eyepiece tube of the microscope can be adjusted, to facilitate observation and operation.

Rotating eyepiece tube, different microscopes may have different methods, for some, the direction is confirmed when installing the eyepiece tube of the microscope, for some, by rotating the body of the microscope, and for some, by rotating the support member on the support or holder of the microscope.

E-ArmClose ΛUsually the universal joint is called E-Arm, i.e., Easy-Arm, also known as Universal Arm. Many people in the industry call it Bonder Arm, which refers to the components that connect the microscope on the COG Bonding Machine.

At the tail of the E-arm there is a standard 5/8 inch (0.625 inch, 15.875mm) connector. The connector can be moved freely in both horizontal and vertical directions, and can also be fixed at an angular position in the vertical direction to facilitate microscope observation from different angles.

E-arm can be connected to various kinds of microscope stands with 5/8-inch adapters, such as boom stand, flexible arm etc. It is also possible to connect various kinds of microscopes by adding or replacing different adapters. Note that, in general, these stands themselves are not directly configured with this E-arm, and separate purchase is necessary.

Dia. 76mm Scope HolderClose ΛThe 76mm stand scope holder is the most popular microscope body adapter size, suitable for stereo microscopes produced by most manufacturers.

Because this stand scope holder is very common, some special-sized microscopes can also borrow and use this stand, but only need a specific adapter to connect the microscope body with a diameter of less than 76mm.
