Device for measuring intensity distribution of longitudinally extended light source, has light-absorbing cooling body, which is arranged in direction of longitudinal extension of light source and in radiation direction of light source

摘要

The device has a light-absorbing cooling body (8), which is arranged in the direction of the longitudinal extension of the light source and in a radiation direction of the light source directed to the line of action. The cooling body has absorption elements in the region of the radiation (6) of the light source. The absorption elements are arranged in a row in the direction of the longitudinal extension of the light source and over the entire length of the light source. The absorption elements are provided with temperature sensors, which are connected with an evaluation unit.
