Spectralon diffuse reflectance standards are available individually and in sets consisting of a diffuse white standard, and a selection of diffuse gray standards. Each is supplied with complete diffuse reflectance data from 250nm to 2500nm. Each standard is housed in a durable delrin holder with a protective cover. Spectralon diffuse white standards offer the highest diffuse reflectance values of any known substance. These durable, chemically inert and washable standards have typical reflectance values of 95% to 99% and are spectrally flat over the UV-VIS-NIR spectrum. All Spectralon materials are typically flat to +/- 4% over the range of 250 to 2500 nm and +/- 1% over the photopic region of the spectrum. Spectralon reflectance standards and materials are highly lambertian over their effective spectral range. Spectralon SRM-99 reflectance material is the most lambertian reflector available for use over the wavelength range from 250 - 2500 nm. All reflectance calibration tests are performed in the Reflectance Spectroscopy Laboratory at Labsphere. The standards used in these tests are directly traceable to The National Institute of Standards and Technology.
