Abstract

The invention relates to an optical instrument making and improves image quality by improving the correction of field aberrations. The eyepiece of the microscope includes a collective component in the form of a flat convex lens I and an eye component consisting of two identical flat lens lenses 2 and 3. Lenses 1–3 have equal optical forces and are mounted so that they can move along the optical axis of the ocular. Lenses 2 and 3 have convex surfaces facing towards each other. The relationship is given by which the distance between the main planes of the collective and ocular components is determined. I zp f-ly, 1 ill. with S (L with

Description

eleven

This invention relates to an optical instrument, namely, to the eyebrows of microscopes.

The purpose of the invention is to enhance the image quality by improving the correction of field aberrations and changing the visible magnification, the ocular, while maintaining the image quality.

The drawing is a schematic diagram of the ocular for magnification

The eyepiece of the microscope consists of successively located along the beam from the object of the collective component, made in the form of a flat-convex lens 1, and an ocular consisting of two identical flat-convex lenses 2 and 3, convex surfaces facing towards each other. the optical power of the lenses 1, 2, 3 are equal between. This layout of the Optical Scheme allows the eyepiece to
