Lambertian (diffuse) reflectance from 250 – 2500 nm.
Reflectance percentage between 2% to 99%.
Spectrally flat over the UV-VIS-NIR spectrum.
Optically flat to +/- 4% over the photopic region of the spectrum.
The calibrated reflectance standards are NVLAP accredited.
The reflectance of Spectralon® is >99% over a range of 400 to 1500 nm and >95% from 250 to 2500 nm.
The Spectralon standards are suitable for determining the accuracy and linearity of reflection spectrophotometers and calibration of optical instruments.
The diffuse reflectance standards are available in a set of four or eight reflection standards with different reflectance percentages, in a diameter of 1.25 or 2 inches, calibrated or uncalibrated.
The diffuse reflectance standards are also available separately in the webshop.
