The model 268UVA is a low-profile sensor designed for applications with limited mechanical clearance. The unit is optimized for 365nm measurement in the UVA portion of the spectrum (320-400 nm) via an integrated filter, and provides Irradiance measurements in W/cm2.

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.
