The model 265 products consist of luminance sensors including an occluder ring for blocking ambient light. Ideal for measurement of displays, these sensors are designed with spectral responsivity that matches the human visual system, incorporating a silicon detector combined with a spectrally matched photometric filter.
The luminance head was specifically designed for measuring display brightness. Its integral lens provides a fixed field-of-view of 13 degrees and a soft rubber light shade eliminates errors due to ambient light and keeps the display from being scratched during measurement.
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.
