ABSTRACT:
The measurement head is equipped with the ray selection unit, which is entered by the rays emitted by the light unit under test. These rays enter the passages and are detected by the ray detection unit when they exit the ray selection unit. Said ray detection unit provides signals corresponding to the detected image, which are sent on for further processing. A precise measurement of the light unit is possible using the inventive light tester.
