Spectral Reflectance Standard: The SRS-2, ideal for conversion of illuminance to luminance or spectral irradiance to radiance, is a highly stable, neutral white reflectance standard. It has Lambertian properties over wide angles and can optionally provide bi-directional reflectance data over a spectral range of 300 to 900 nm.
