Diffuse Reflectance Standards

Labsphere's award-winning Spectralon® forms the basis of our diffuse reflectance standards. The range includes standards of reflectance for the 250-2500nm range (white and grey-scale), colour, wavelength and fluorescence. All are characterised by stable, Lambertian (diffuse) reflectance; compared with glossy artefacts, diffuse reflectance standards provide for stable, consistent reflectance regardless of instrument alignment or illumination and viewing geometries. For the IR (2.5-15µm) we also offer Infragold diffuse reflectance standards. Our standards are used to calibrate colorimeters, reflectometers, spectroradiometers, BRDF scatterometers, UV-VIS spectrophotometers and FTIR spectrometers.
