Introduction to the Main Mechanical Components of Inverted Microscopes
(1) Mirror holder: It is the base of a microscope, used to support the entire mirror body.
(2) Mirror column: It is the upright part above the mirror base, used to connect the mirror base and the mirror arm.
(3) Mirror arm: One end is connected to the mirror column, and the other end is connected to the lens barrel. It is the hand holding part when picking up and placing microscopes.
(4) Tube: Connected to the front upper part of the mirror arm, the upper end of the tube is equipped with an eyepiece, and the lower end is equipped with an objective converter.
(5) Objective lens converter (rotator): attached to the bottom of the prism housing, it can rotate freely. There are 3-4 circular holes on the disc, which are used to install the objective lens. By rotating the converter, different magnifications of the objective lens can be exchanged. When a knocking sound is heard, observation can be carried out. At this time, the optical axis of the objective lens is precisely aligned with the center of the through hole, and the optical path is connected.
(6) Mirror stage (stage): Under the lens barrel, there are two shapes: square and circular, used to place glass slide specimens. There is a light hole in the center. The microscope we use is equipped with a slide specimen pusher (slide pusher) on the mirror stage, and there is a spring clip on the left side of the pusher to hold the slide specimen. There is a pusher adjustment wheel under the mirror stage, which can move the slide specimen in the left, right, front and back directions.
(7) Adjuster: It is a screw of two sizes installed on the mirror column, which moves the mirror platform up and down during adjustment.
① Coarse adjuster (coarse spiral): The large spiral is called a coarse adjuster, which can quickly and significantly raise and lower the stage when moving, so it can quickly adjust the distance between the objective lens and the specimen to present the object in the field of view. Usually, when using a low magnification mirror, the coarse adjuster is used to quickly find the object.
② Fine adjuster (fine spiral): A small spiral is called a fine adjuster, which can slowly raise and lower the stage when moving. It is often used when using high-power mirrors to obtain clearer images and observe the structure of specimens at different levels and depths.
