The model 247 radiometric sensor includes a precision radiometric filter for flat response from the blue to the near-infrared. This sensor assembly is popular for its high linearity and low noise performance.

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.
