The two main parts of a microscope
(A) the mechanical parts of the microscope
1. lens barrel
For the upper part of the microscope round hollow long tube, the mouth of the upper end of the eyepiece installed, the lower end and the objective lens converter connected. The role is to protect the imaging light path and brightness.
2. Converter
Fixed in the lower end of the barrel, divided into two layers, the upper layer of fixed immobile, the lower layer can be free to rotate. There are 2 to 4 holes on the converter, used to install different magnification of the low or high objective lens.
3. Coarse focusing screw
Located on the top of the arm, it can be rotated to move the lens barrel up and down to adjust the focus.
4. Fine focusing screw
Located at the bottom of the arm, it has a smaller range of movement than the coarse focusing helix and allows for fine focus adjustment.
5. Mirror base
It is a horseshoe-shaped metal base located under the arm, at the bottom of the microscope. It is used to stabilise and support the mirror body.
6. Mirror column
A short column that stands upright from the lens base. It is attached to the arm and the base of the microscope to support the arm and the stage.
7. Tilt Joint
The tilt joint (not to exceed 45°) is convenient for observation. However, it is forbidden to use the tilting joint when observing with a temporary seal, especially when the mount contains acidic reagents, so as to avoid contamination of the lens body.
8. Carrier Table
It is a metal platform that extends from the mirror arm to the front. It is square or round, and is the place for placing slide specimens. Its centre has a light hole, in the light hole of the left and right there is a flexible metal clip, used to press the slide. More ** microscopes often have a propeller on the stage, which consists of a clamping clip and a propelling screw, which, in addition to clamping the slides, allows the slides to be moved on the stage.
