The Model 211 Photometric sensors are our standard base unit, designed with spectral responsivity that matches the human visual response. The products incorporate a silicon detector combined with a spectrally matched photometric filter.  An integrated cosine filter significantly reduces directional sensitivity for ease of use.

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.
