RW-37&SRT-M37-L light detectors for polychromatic radiance

Irradiance Detectors with Radiance Attachment

A cost effective strategy to perform both irradiance and radiance measurements is to outfit RW-37 and UV-37 series irradiance detectors with front lens adapters. The radiance adapters limit the field of view of the irradiance detector to enable radiance measurement in W/(m²sr) of larger area radiance sources.


Standard and UV Enhanced Lens Adapter

Beside the SRT-M37-L adapter with glass lens Gigahertz-Optik GmbH offers the SRT-M37-L-UV adapter with UV transparent quartz lens for use with UV-37 detectors.


Simple Assembly

The SRT-M37L series front lenses attach to the front of the 37-type type detector housings using the SRT-M45/37 base mount which fits onto the detector housing and is held in place with set screws. The SRT-M45/37B is internally threaded (M37x1) so that the externally threaded SRT-M37L front lens can be screwed into it. The SRT-M45/37B base mount has an M6 and standard camera (1/4”-20 BSW) threaded hole for tripod or bench post or to fixture the device into an application.


1° to 10° Selectable Field-of-Views

Front lenses with 1°, 2°, 5° and 10° are available.


Traceable Calibrations

Lens and detector assembly is calibrated in radiance sensitivity in W/m²sr at Gigahertz-Optik’s Calibration Laboratory for Optical Radiation Quantities.
