The model 221 radiometric sensor is our standard silicon sensor.  It can be combined with a wide range of accessories including optical filters, diffusers, integrating spheres and spacers.

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.
