Introduction to Microscope Eyepieces
The eyepiece is a visual optical device used to observe the image formed by the front optical system, and is an integral part of visual optical instruments such as telescopes and microscopes. In order to eliminate aberration, the eyepiece is usually composed of several lenses, which have a large field of view and viewing angle magnification.
The function of the eyepiece is only to enlarge the object image completed by the objective lens. The most common eyepiece is the Huygens eyepiece. In order to compensate for the aberration caused by the objective lens during the imaging process, a compensating eyepiece can be used.
The lens barrel of the compensating eyepiece is engraved with the letter "C" in English and "K" in Russian. This is the prefix of the word compensation or KOM1IeHCaLZN. For the observer's visual pleasure and wide field of view, major manufacturers sell wide field of view high eye point eyepieces. The field of view value of this eyepiece has reached 25mm, and the person wearing glasses can observe without taking off the glasses. The casing of this eyepiece is engraved with the image of the eyeglass frame. English photoeyepiece or Russian (DOTO) are engraved on the special long-focus eyepiece used for microphotography. The focusing telescopic eyepiece can be used in the focusing of the phase plate and ring diaphragm of the phase contrast microscope. This eyepiece is a double-layer mirror Simple set, extendable and retractable eyepiece. It is best to choose the goniometric eyepiece on the polarized light microscope. The inside of the goniometric eyepiece is equipped with a cross line, and the outside of the mirror is engraved with a 3600-scale turntable and the stage. 3600 scale is suitable for use.
It is very convenient to use the teaching eyepiece in the teaching of histology. This is an eyepiece that splits light with a prism above the mirror and two or more eyepieces observe a target at the same time. There is also an indicator needle inside the eyepiece. So-called micrometer eyepieces are actually eyepieces that mount an eyepiece micrometer in any kind of eyepiece.
