Eyepiece for OLED
The eyepiece is a visual optical device used to observe the image formed by the front optical system. It is an integral part of the telescope, microscope and other visual optical instruments. Its main function is to re-amplify the real image obtained from the magnification of the eyepiece. In order to eliminate aberration, the eyepiece is usually composed of several lenses and has a large field of view and angle magnification.
