“LEDs and lasers are rapidly replacing wideband light sources, such as mercury or xenon lamps, in a variety of applications,” commented Dr. Efi Rotem, Project Manager, Ophir Photonics. “However, traditional radiometers are designed for wideband sources. Their spectral response is not flat, therefore, they are not suitable for measuring narrowband sources. The PD300RM is designed for LED and laser sources. The sensor allows the user to enter the specific wavelength, and then automatically adjusts to provide the correct measurement at that wavelength.”
The PD300RM is available in two models: the PD300RM-UV, which is suitable for irradiance levels of 15nW/cm2-300mW/cm2, and the PD300RM-8W, which is suitable for irradiance levels of 0.2µW/cm2-8W/cm2.
