Product Specification

SOL-LUM Solar Radiation Luminosity Sensor Description
The Luminosity Sensor is a photometric sensor designed for measurements of lighting conditions when the eye is the primary receiver. Applications include measurement of light in work areas, and from television screens.

The sensor uses a filtered silicon photodiode to provide a spectral response that matches the CIE curve within +5% under most light sources. This photodiode and filter combination is placed within a fully cosine-corrected sensor head to provide the proper response to radiation at various angles of incidence.

The Luminosity Sensor is mounted on a leveling base and is available with either a flat base or plug-in mount to fit the RainWise Quadpod or Monopod mounting systems. It is manufactured of high stability silicon (detector), aluminum, stainless steel and PVC (base for RainWise Mount).
