Device for measuring light intensity |
摘要 |
A light-sensitive sensor (3) detects light that passes through a directional device (4). An attenuator attenuates the light arriving at the sensor or the light passing through the directional devices, so that a predetermined incident light intensity is not reached. The attenuator is formed as a reflective surface (7).
