Mechanics of a general optical microscope
(1) Mirror base: is the base of the microscope, used to support the entire mirror.
(2) Mirror pillar: It is the upright part on top of 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 mirror tube, which is the part of the hand grip when taking and placing the microscope.
(4) Mirror tube: attached to the upper front of the mirror arm, the upper end of the mirror tube is equipped with an eyepiece, the lower end of the mirror tube is equipped with an objective lens converter.
(5) Objective lens converter (rotator) referred to as "rotator": connected to the bottom of the prism shell, can be freely rotated, there are 3-4 holes on the disc, is the installation of the objective lens parts, rotating the converter, you can switch to a different magnification of the objective lens, when you hear the sound of touching the knocking sound, then you can carry out the observation, at this time, the optical axis of the objective lens is exactly aligned with the light-through hole centre. At this time, the optical axis of the objective lens is exactly aligned with the centre of the through-hole, and the optical path is connected. After converting the objective lens, it is not allowed to use the coarse adjuster, but only use the fine adjuster to make the image clear.
(6) Mirror stage (carrier stage): below the lens barrel, the shape of the square, round two kinds, to place the slide specimen, the centre of the aperture, the microscope we use is equipped with a slide specimen propeller (pusher), the propeller has a spring clip on the left side of the specimen to clamp the slide specimen, under the stage has a propeller adjusting wheel, so that slide specimens for the left and right, forward and backward direction of the movement.
(7) Adjuster: It is a spiral of two sizes mounted on the mirror column, which moves the mirror table up and down when adjusted.
(1) coarse adjuster (coarse focusing spiral): large spiral called coarse adjuster, moving the mirror table for rapid and large-scale lifting, so it can quickly adjust the distance between the objective lens and the specimen to make the object presented in the field of view, usually in the use of low-magnification mirror, the first use of coarse adjuster to quickly find the object.
② fine adjuster (fine focusing screw): a small spiral called fine adjuster, moving the mirror stage can be slowly raised and lowered, mostly used in the use of high magnification, so as to get a clearer image, and to observe the different levels of the specimen and the different depths of the structure.
