Abstract

A scanning accessory for a microscope/photometer, where the photometer system is mounted to or inside an intermediate tube of the microscope and the intermediate tube is provided near or at the one end of its lower side with a coupling system for mounting to the stand and at the opposite side with a coupling system for mounting the ocular, the photometer being inserted into the intermediate tube's beam by means of a beam splitter, a subsequent triple mirror and an ocular. The scanning accessory preferably periodically changes the relative position of the transmitted beam (4a) and of the image (76a) or (76b) of the measuring stop (42) with respect to the microscope image (72) and is located between the photometer system (41-46) and the beam splitter (22) mounted inside the intermediate tube (2) of the microscope for the purpose of enlarging the application possibilities of the microscope/photometer.
