¡ö structure of the optical microscope
Ordinary optical microscope, the structure is divided into three main parts: the part of the machinery, part of the lighting and optical parts.
¡ô part of the machinery
(1)-Block: The microscope is the base to support the entire body mirror.
(2) Mirror column: Block is a mirror above the vertical part of the seat and mirrors designed to connect the mirror arm.
(3)-arm: mirror at one end even columns, even at the end of the tube, is the pick-and-place parts of a microscope at hand.
(4) tube: even before the boom in the mirror above the upper end of the tube with eyepiece, with the lower end of the objective lens converters.
(5) objective lens converters (rotator): Access to the bottom of the prism of the shell, are free to rotate, the disc has a 3-4 hole, the objective is to install the site, turning converter, you can change multiple different lens, when the hearing Touch to the sound of knocking, can be observed at this time lens axis at exactly light-hole centers, optical access.
(6) Jingtai (set-Taiwan): bottom of the tube, well-shaped, round two, to put glass samples, a central light-hole, we used a microscope slide with its mirror on the stage booster sample ( Push-on-chip), the propeller on the left side of Spring have to clamp slide specimens, a propeller-stage round-conditioning can make a specimen slide around, before and after the direction of the movement.
(7) Regulator: mirror is mounted on a column of the size of two spiral, so that when adjusting for Jingtai up and down the direction of the movement.
¢Ù regulator rough (rough spiral): The crude screw adjustment that, when the mobile Jingtai can be relatively large and rapid rise and fall, they are able to quickly adjust lens and the distance between the specimens so that the object shown in the field of vision, usually in the The use of low-fold mirror, the first rough regulator quickly find objects.
¢Ú small regulator (leptospirosis): Fine, said the small spiral regulator, can move slowly Jingtai take-off and landing, in the use of high-power lens used in order to get a clearer images, and to observe the specimen at different levels and at different depths Structure.
(8) converter: can use when converting multiple of different lens. Conversion lens, the regulator does not allow the use of rough, with only small adjustment, as is clear.
¡ô part of the lighting
Jingtai mounted on the bottom, including mirrors, set-ray.
(1) mirrors: mirror mounted on the top seat may be made to rotate in any direction, it is flat, concave on both sides, which is the source of light reflection to the condenser, and then by the light-hole specimen lighting, concave mirror condenser The role of strong and weak light for the use of the time, the role of the weak plane mirror condenser, for the use of strong light.
(2) Set-ray (condenser) at the bottom of the Jingtai-ray device on the shelves by the condenser aperture and composition, its role is to focus light to be observed on the specimens.
¢Ù condenser: a film or lens, the light gathered from the role to strengthen the specimens of lighting and light into the lens, a mirror Zhupang adjustment screw, turning it off and landing condenser, in order to adjust vision In the strength of the brightness.
¢Ú aperture (iris aperture): condenser in the microscope side by dozens foil, its a lateral out, it can promote the adjustment of the opening of its size in order to adjust the amount of light.
¡ô optical parts
(1) eyepiece: mounted on top of the tube, usually equipped with a 2-3, engraved above 5 ¡Á, 10 ¡Á or 15 ¡Á symbol to show its magnification, the equipment is generally 10 ¡Á the eyepiece.
(2) objective: mounted on the lower end of the tube rotator, the general has a 3-4 lens, the shortest engraved with "10 ¡Á" as a symbol of low-fold mirror, engraved with a longer "40 ¡Á" symbol of For high-power microscope, the longest engraved with "100 ¡Á" symbol of the oil-for, in addition, the high-and oil-plus there are also often different colors around the line as a sign of distinction.
Magnification of the microscope is the magnification of the objective lens and the eyepiece magnification of the product, such as the objective for the 10 ¡Á, for the eyepiece 10 ¡Á, its magnifying power for 10 ¡Á 10 = 100.
