The model S2575R Integrating Sphere consists of a model 262 Silicon sensor coupled to a model 2575, 50 mm diameter integrating sphere. The unit incorporates an internal radiometric filter and provides flat response from the blue to the near-infrared with measurements in W or mW.

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.
