Abstract

PURPOSE: To change the quantity of light of light source so that the quantity of observation light be constant by receiving the quantity of light in the optical path of a microscope with a photo detector and adjusting a dimmer.
CONSTITUTION: In the structure, part of observation light is designed to pass through an objective lens 8 and then pass through an inclined prism 9 in the lens barrel. The light passing through this prism 9 is reflected by a reflecting mirror 12, and is then led to a photo detector 13. The quantity of light detected by this photo detector 13 is compared with the level 17. A dimmer 14 is adjusted by a control signal 18 based on said comparison, so that the quantity of light in a light source 1 may be changed accordingly.
