Abstract

An arrangement for illuminating a specimen field in an optical instrument for specimen viewing includes: an illumination device, arranged in a housing, including a light source and an illuminating optical system, where a position of the light source or illuminating optical system is adjustable within the illumination device; a setting device including at least one drive system and configured to positionally adjust the light source or illuminating optical system; at least one linkage member connected to the light source or illuminating optical system, where the linkage member includes a coupling member accessible by the setting device from outside the housing; at least one measurement device configured to sense parameters of the light generated by the illumination device; and a control device that is configured to generate positioning commands for positional adjustment of the light source or illuminating optical system by the drive system as a function of the sensed parameters.
