VL-3704 Detector

The VL-3704 is a reasonably priced illuminance measurement head whose photometric responsivity and cosine field of view correspond to the DIN 5032 - Article 7 quality class B. The detector can be combined with all optometers and light meters from Gigahertz-Optik.

Traceable Calibration

The VL-3704 is calibrated in terms of its absolute illuminance responsivity and relative spectral responsivity by the Gigahertz-Optik calibration laboratory for optical radiation measurands. The calibrations are documented in an individually compiled calibration certificate. The design and contents of the calibration certificate are in accordance with the ISO 17025 specifications.
