The model 264 radiometric sensor is our miniature series silicon sensor specifically designed for laser power measurement. It contains an integrated diffuser and reduced aperture for attenuation of optical power. 

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.
