Spectralon® Diffuse Reflectance Standards
Unequalled Lambertian reflectance from 250 – 2500 nm.
Spectralon Diffuse Reflectance Standards offer the highest diffuse reflectance values of any known substance. These durable, chemically inert standards can have typical reflectance values ranging from 2% to 99% and are spectrally flat over the UV-VIS-NIR spectrum. All Spectralon materials are optically flat to +/- 4% over the photopic region of the spectrum.

*Select Product Option First
Spectralon Diffuse Reflectance Standards are available individually and in sets, consisting of a diffuse white standard and a selection of diffuse gray standards. Each standard is supplied with complete diffuse reflectance data from 250 – 2500, every 50 nm. All standards are housed in a durable Delrin holder with a protective cover.
Unmatched Reflectance
Spectralon’s reflectance is generally >99% over a range from 400 to 1500 nm and >95% from 250 to 2500 nm. Spectralon can be doped with black pigment to produce spectrally flat gray scale standards and targets. Spectralon gray scale standards are useful for determining the linearity and accuracy of reflectance spectrophotometers and calibration of various optical instruments, including those used in blood analysis, CCD arrays, and night vision devices.
Consistent
All reflectance calibration measurements are performed in the Reflectance Spectroscopy Laboratory at Labsphere. These measurements are covered by Labsphere’s NVLAP scope of accreditation. The standards used in these tests are directly traceable to the National Institute of Standards and Technology (NIST).
Spectralon® Diffuse Reflectance Standards are available in either 1.25 or 2.00 inch diameters in the following reflectance values: 99%, 80%, 60%, 40%, 20%, 10%, 5% and 2%.
