UV Irradiance Detectors

UV-37 series detectors are high sensitivity irradiance detectors for UV radiometric applications involving polychromatic optical radiation. Each detector is supplied with a diffuser window and shadow ring for a cosine corrected field-of-view. The relevant components of the detector are UV aged prior to calibration to minimize degradation in long term use under UV radiation.The compact low profile 37-type housing fits into tight spaces and includes a M6 tapped hole for post mount stands. A machined V-groove allows other components like quartz radiance barrels to be attached expanding application capability.

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 UV irradiance in Wm and W/cm within the specified spectral sensitivity range is provided.
