Microscope StandClose Λ

Microscope stand have many options depending on the needs, especially stereo microscope stand, there are several factors to consider before choosing:
Stability: microscope stand is used to prop up the microscope body. The stand should be selected according to the size of the microscope mainframe. The stability of the stand determines the stability of the microscope in use, and its various adapters and screws must be tightly locked.
Volume size: limited by the working environment and space of the workbench.
Workspace and scope: the size of the workspace of the object being observed and the height of the object being observed should be considered.
Choice of lighting: some stands are equipped with a light source, but some are not, depending on whether there are conditions to add additional lighting.

Operational requirements:
1. Install the stand as required.
2. Arrange a reasonable fixed position for the stand.
3. Carefully tighten the microscope mainframe.
4. Arrange the location of the additional light source reasonably, and place the electric wire in a position that does not interfere with the work.
5. Connect the various kinds of peripheral devices, such as cameras, monitors, computers and so on.

Track StandClose Λ

Throughout 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.
The size of the stand is generally small, flexible and convenient, and most of them are placed on the table for use, Therefore, together with the post stand, it is also called “desktop or table top stand".
With regard to the height of the stand, most manufacturers usually do not make it very high. If the guide rail is long, it is easy to deform, and relatively more difficult .

Dia. 76mm Scope HolderClose Λ

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

Place the microscope body in a 76mm scope holder, tighten with screws to avoid shaking when the microscope is in use.
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.

Illumination BaseClose Λ

Illumination base is a modular light source component, suitable for microscope stand base that has no light source of itself, and it is usually dedicated components supporting some stands.
Illumination base typically includes at least one bottom lighting, and there are also illumination base that includes the circuit portion of the upper light source.

Stand Throat DepthClose Λ

Stand 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.

Coaxial Coarse/Fine FocusClose Λ

Focus mechanism, the coarse / fine focus knobs are in a coaxial center position, they are connected together by a gear reduction mechanism, which can be coarse/ fine focus adjusted at any time during the entire stroke.
Generally, the coarse focus diameter is relatively big, which is inside close to the body of the microscope, and the fine focus diameter is relatively small, which is outside of the body of the microscope. Coarse focus adjustment is used to quickly move to find the image, and the fine focus adjustment is used to finely adjust the clarity of the image. Generally, the minimum read value of the fine focus adjustment can be accurate to 1 micron, and single circle can reach a stroke of 0.1 mm. Mechanical fine focus plays a very important role in the accuracy of the microscope resolution. If the fine focus accuracy is not enough, or cannot be stabilized at the sharpest focusing position, the image will be out of focus and become blurred.
The tightness of coarse focus is generally adjustable. Generally, on one side of the knob (usually on the right side), there is a textured knob on the inside of the coarse knob, which is tightened if rotated clockwise; and loosened if rotated counterclockwise.

In the process of focusing, direct focusing should not be on the objective of high magnification; instead, find the object of low magnification first, and gradually adjust to high magnification. Usually, the coarse focus knob is rotated first, and when the objective lens is gradually lowered or the platform is gradually rising, find the object, and then adjust with the fine focus, until the object image in the field of view is clear. Generally, when changing from low magnification to high magnification objective, one only need to slightly adjust the fine focus knob to make the object image clear. During the process, the distance between the objective and the specimen should be observed from the side, to understand the critical value of the object distance between the lens and the specimen.
When using a high magnification objective, since the distance between the objective and the specimen is very close, after the image is found, the coarse focus knob cannot generally be used, and the fine focus knob can only be used to avoid excessive distance of movement, damaging the objective and the slide or specimen.

By using the characteristics of the fine focus, the height or thickness of the observed object can be roughly measured under the microscope, such as measuring the thickness of the cell or tissue, the thickness of the cover glass, and the thickness of small objects that cannot be measured by various conventional measuring instruments.
Method of measurement: place the object to be measured at the center of the field of view of the stage. After the image is clearly focused, try to use the highest magnification objective as much as possible, and align the adapter of the top feature point of the object to be measured. After adjusting clear, record the position of scale of the fine focus knob. Then, move the objective down to the adapter of the lowest feature point of the object to be measured, and record the position of scale of the fine focus knob. Then, according to the above fine focus, record the number of rounds of movement, and based on the parameters of conversion of each round into stroke (see the microscope fine focus knob parameters), the number of rounds is converted into the total stroke, which is the height of the object to be measured. If it is repeated a few times for average, a more accurate measurement can be obtained.

Focusing Knob Tightness AdjustableClose Λ

Different microscope bodies, different human operations, and different requirements for observation and operation, all require adjustment of the pre-tightening force of the stand that support microscope body.
Facing the stand just right, use both hands to reverse the force to adjust the tightness. (face the knob of one side just right, clockwise is to tighten, counterclockwise is to loosen)
In general, after long-time use, the knob will be loose, and adjustment is necessary.

Microscope PlateClose Λ

According to different objects to be observed, the appropriate platen should be selected. The microscope plate materials include black and white, black and white finish; transparent glass, frosted glass, metal, etc.
Standard stands are generally configured with a suitable microscope plate, but different plates may need to be purchased separately.
Black and white microscope plate are made of general plastics, and the different backgrounds in black and white make the object more prominent.
Finish microscope plate eliminates reflections during observation.
Transparent glass plate is used when observing transparent or translucent objects, and the use of transmitted light source is to make the light penetrate the object to be observed as much as possible.
Finish glass plate, with its rough glass surface, can make the transmitted light more uniform and create a diffusing effect, avoiding exposure of the light shadow of the filament directly onto to the observed object.
Metal plate, relatively more solid, is more suitable when it is necessary to operate and cut.
Microscope plate is generally round shaped, on one side of the base there is a spring clip. When installing, align the plate with the clamp and push it in, and then press down the other end, so that the plate is smoothly embedded in to the circular card slot of the bottom plate.
When removing, grab the other end of the clip, push and lift up the plate.

PackagingClose Λ

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.
