Abstract

Illumination of the object of study is an important part of the research by optical methods. In some devices, it is necessary not only to illuminate the object of study completely, but also to achieve uniform illumination. To do this, in such optical systems as biological microscopes, an illuminating optical system of the Köhler type is used. Modern research in the field of improving the classical Koehler scheme has shown that they are aimed at improving the optical and energy characteristics, and do not take into account the dimensions of the lighting system. In some new models of microscopes, to reduce overall dimensions, only an LED with a frosted diffuser is used as an illuminating optical system, providing complete, but not uniform, illumination of the object. In this work, an illuminating optical system with reduced overall dimensions was developed. The stages of calculation of the collector and condenser of the lighting system are shown.
