NORTH LOGAN, Utah, March 10, 2015 — A calibrated irradiance and dosage sensor, the PD300RM from Ophir Photonics measures narrowband LED and laser sources between 200 and 850 nm. The sensor automatically adjusts to provide correct power and energy measurements based on the wavelength designated by the user. This delivers a more accurate reading than traditional radiometers used to measure wideband light sources like mercury and xenon lamps. The PD300RM also incorporates a cosine corrected quartz glass diffuser, suitable for UV radiation. Two models are available: the PD300RM-UV for irradiance levels 15 nW/cm2 to 300 mW/cm2, and the PD300RM-8W for irradiance levels 0.2 μW/cm2 to 8 W/cm2.
