In most Blue Light Hazard applications radiance is measured except in spot source configurations where irradiance measurements are appropriate. The UV-3709 is a single sensor blue light hazard detector with spectral response in the wavelength range from 380 to 550nm. It is recommended for measuring sources with low UV-A and Red radiation content.
Traceable calibration
Calibration of the detector blue light hazard effective (W/m²) responsivity is performed by the Gigahertz-Optik GmbH calibration laboratory for optical radiation measurements quantities. As with all light detectors supplied by Gigahertz-Optik calibration of absolute detector responsivity as well as detector individual measured relative spectral responsivity data is included.
