The Model 288 Photometric Sensor features an integral filter / sensor mount, that can be used in constrained spaces due to its reduced diameter. The model consists of a standard series silicon sensor and a spectrally-matched photometric filter to simulate the response of the human visual system and match the spectral response of a standard observer.  

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.
