The model S2575 Integrating Sphere consists of a model 260 silicon sensor coupled to a model 2575, 50 mm diameter integrating sphere. The unit provides 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.
