The PD300R-UV is a wide spectral range circular geometry photodiode laser measurement sensor. It has a 10mm aperture and a removable filter. Without filter, its spectral range is from 200 to 1100nm and its power measuring range is from 20pW to 3mW. With filter the spectral range is 220nm to 1100nm and the power range is 2µW to 300mW. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.
