Modular Light Detectors

MD-37 series modular light detectors feature a M30x1 threaded front interface for fast and simple screw-on assembly of mating accessory components. For multi-purpose use the MD-37 series detectors offer a wide range of base photodiode detector types and different active areas. This provides a great degree of freedom in selecting a spectral sensitivity, light responsivity and speed of response for a specific job.

PD-93 series modular light detectors are built using large, 1 cm2 photodiodes for higher sensitivity light measurement applications. PD-93VL and PD- 93RW photometric and radiometric correction filters for illuminance and integral irradiance measurements can be combined with the PD detector and its 20mm diameter cosine diffuser.

The detectors are supplied with a 2m long coaxial cable with selectable -1, -2 or -4 type connector for use with Gigahertz-Optik's range of optometers. Internationally traceable calibration & certification of illuminance in lux and UV irradiance in Wm and W/cm within the specified spectral sensitivity range is provided.
