How much do you know about the mechanical part of the optical microscope
(1) Mirror base: It is the base of the microscope to support the entire mirror body.
(2) Mirror column: It is the upright part above the mirror base, which is 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, which is the hand-held part when taking and placing the microscope.
(4) Lens barrel: connected to the upper front of the lens arm, the upper end of the lens barrel is equipped with an eyepiece, and the lower end is equipped with an objective lens converter.
(5) Objective lens converter (rotator): It is connected to the bottom of the prism shell and can rotate freely. There are 3-4 round holes on the disc, which are the parts for installing the objective lens. Turning the converter can change the objective lens of different multiples. Observation can only be carried out when there is a knocking sound. At this time, the optical axis of the objective lens is just aligned with the center of the light hole, and the optical path is connected.
(6) Mirror stage (stage): Under the lens barrel, there are two shapes, square and round, for placing slide specimens. There is a light hole in the center. The microscope stage we use is equipped with a slide specimen pusher ( Pusher), there is a spring clip on the left side of the pusher, which is used to hold the slide specimen, and there is a pusher adjustment wheel under the stage, which can make the slide specimen move left and right, front and back.
(7) Regulator: There are two types of screw, large and small, installed on the mirror column. When adjusting, the mirror table can move up and down.
① Coarse adjuster (coarse spiral): The large spiral is called the coarse adjuster, which can make the stage move up and down quickly and in a large range, so the distance between the objective lens and the specimen can be quickly adjusted to make the object appear in the field of view, usually When using a low-magnification lens, first use the coarse adjuster to quickly find the object.
②Fine regulator (fine spiral): The small spiral is called the fine regulator, which can make the stage slowly rise and fall when moving, and is mostly used when using a high-power lens, so as to obtain a clearer object image, and to observe different layers and different depths of the specimen Structure.
