Photometry

Photometry is the study and measurement of the intensity of visible light. The visible light spectrum spans from approximately 400nm to 760nm. Photometric applications include research on lighting levels, Photopic & Scotopic research, and illumination efficiency.

Measure Photopic and Scotopic light according to the action spectrum of the human eye using PMA2100 research grade radiometer along with our PMA2130 Photopic (daylight illumination) Detector and our PMA2131 Scotopic (night vision) detector.

All radiometers and detectors are calibrated to NIST standards.
