Sensor measures narrowband LED & laser sources
A calibrated irradiance and dosage sensor, which measures narrowband LED and laser sources between 200 and 850nm, has been introduced by Ophir Photonics. The PD300RM automatically adjusts to provide correct power and energy measurements based on the specific wavelength designated by the user. This delivers a more accurate reading than traditional radiometers. The sensor also incorporates a cosine corrected quartz glass diffuser, suitable for UV radiation.
"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.
