The function of the eyepiece is only to magnify the object image completed by the objective lens. The most common eyepiece is the Huygens eyepiece. To compensate for the aberrations caused by the objective lens during imaging, a compensating eyepiece can be used. The lens of the compensating eyepiece is engraved with the English "C" and the Russian "K" letter. This is the prefix of the word compensation or KoMneHCaQM.
In order to make the viewer's visual pleasure a wide field of vision, major manufacturers sell wide-field high-point eyepieces. The field of view of this eyepiece has reached 25 mm, and the wearer can observe it without having to take off the glasses. The eyeglass frame is engraved on the outer casing of the eyepiece. The special long focal length eyepiece for photomicrography is engraved with English photoeyepiece or Russian q0TO. The focusing plate of the phase contrast microscope and the focusing of the ring diaphragm can be used to adjust the telescopic eyepiece. This eyepiece is a two-layer lens tube. A set of eyepieces that can be stretched and contracted.
It is best to use a goniometer eyepiece on a polarized light microscope. The inside of the angle measuring eyepiece is lined with a cross. The outside of the mirror is engraved with 360. The scaled turntable is matched to the 360° scale of the stage. It is convenient to use the teaching eyepiece on the teaching of histology. This is an eyepiece that uses prism splitting above the mirror and two or more eyepieces to observe one target at the same time. An indicator pin is also mounted inside the eyepiece. The so-called micrometer eyepiece actually mounts the mirror of the eyepiece micrometer in any kind of eyepiece.
The objective is the most expensive component for the McAudi microscope. The price of a high performance objective lens is 1/3-1/2 of the microscope itself. Because the most basic performance of the microscope - imaging and resolution - depends on the objective. In order to eliminate the spherical aberration and chromatic aberration in the imaging process, the lens group of the objective lens is developed from a single lens to a multi-layer composite lens group. The 3-4 lens has been added to 7-9 lenses or lens complexes. The objective lens is engraved with the performance of the objective lens, the mirror ratio of the objective lens, the magnification and the marking of the special objective lens. The outer surface of the achromatic objective lens is engraved with English, German, French Achromat or Russian AXP. The objective lens can eliminate the chromatic aberration caused by red and blue light in the spectrum and cannot eliminate the chromatic aberration formed by other colored lights.
The apochromatic objective lens is the best performing and most expensive objective lens. Its outer casing is engraved with English, German, Apochromat (short Apo) or Russian Ail. Typeface. The lens material is good, the lens group has the most layers, and the combination is accurate to eliminate the chromatic aberration caused by red light, yellow light and blue light. This objective lens can achieve the highest performance of an optical microscope when used with a compensating eyepiece.
The fluorite objective lens is engraved with the words Fluormat (or Fluur) in English, German and French. This is an objective lens that is transparent to ultraviolet light and is dedicated to fluorescence microscopes. If used as a normal objective, the resolution is too low.
The flat image field is engraved with the word Planochromat. Opton sells flat-field fluorite apochromatic objective (Plan-Neofluor), flat field apochromatic objective lens (Plan-Achromat), flat field fluorite achromatic achromatic objective lens (Plan-Neofluorpol).
The phase contrast microscope must be equipped with a phase difference objective. This objective is engraved with the words Pha or Russian in English, German and French.
A monochromate lens is a precious objective lens made of molten crystal for all lenses. This objective lens is UV-transmissive for UV interference microscopy or for UV microscopy spectrophotometers. If such an objective lens cannot be used, it can be replaced by an apochromatic objective lens.
