Abstract
A photometer tube for a microscope contains several switchable reflectors (5, 11). By the appropriate use of these, the ray path (c) for the back-illuminated measuring field stop (7) is reflected out of the photometry ray path (b) and is conducted to a second image inlet (32) of a beam splitter prism or prism slide. Various switchable elements (mirrors 5 and 11; stop 4; prism 2/22) in the tube are electrically driven and are centrally actuated from a control unit.
