[A method of microphotometry with TV-image analysing systems (author's transl)]

In scanning microphotometry only a small spot in the specimen is illuminated at the same time. However, lamp and optical system are designed to transfer 10(5) to 10(6) times more information at once. It is shown, that correct and reproducible results can be attained with stimultaneous illumination of the field received by a TV-camera. It is necessary to calibrate for stray light. Thus the high speed of measurement of TV-Systems can be used for microphotometry.
