The model 2153V-12.0 is our standard Luminance sensor with an integral lens that provides a fixed field of view of  12.0 degrees (other FOV’s available on request, please refer to specifications).  It is ideally suited for measurement of the brightness of diffuse surfaces or uniform light sources, such as the intensity of displays.

Our wide range of optical power meters, photometric and radiometric sensors is complemented by ISO/IEC 17025 accreditation by NVLAP (NVLAP lab code 200823-0), resulting in unmatched performance and custom configuration as required.
