The PMA2106 detector provides precise measurement of non-Weighted UVB radiation from sunlight and artificial light sources. The detector has an angular response that is very close to an ideal cosine function (Lambertian response), making it suitable for measuring diffuse radiation or radiation from extended light sources. The measured results can be displayed as mW/cm2 or W/m2. The high dynamic range allows the instrument to measure radiation intensity in the range of 0.001 mW/cm2 to 200mW/cm2.
