The model 268R is a low-profile sensor designed for applications with limited mechanical clearance. An integral flat filter / diffuser provides flat response from the blue to the near infrared, with measurement units of Watts 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.
