Photodiode
The sensor used in PHOTASGARD ® light intensity sensors (photodiode) was specifically adapted to the sensitivity of the human eye. Its greatest
sensitivity is in the range of 350 nm to 820 nm. Therefore with its special filter the sensor is predestined for exposure measure ment of daylight
and ⁄ or for measuring artificial light of high colour temperature (similar to sunlight).
