The model 268P is a low-profile illuminance sensor designed for applications with limited mechanical clearance. These Photometric sensors are designed with spectral responsivity that matches the human visual system, incorporating 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.
