Diffuse Reflectance Standard Calibration Target Package <br/>(T3-R50)

MAPIR offers our compact Diffuse Reflectance Standard Calibration Target Package (T3-R50), which contains 4 reference standard targets of known reflectance. Diffuse and total reflectance percent measurements from 250-2500nm were made using multiple Shimadzu spectrophotometers incorporating an integrating sphere. The lambertian reflectance panels can be captured from any angle thanks to similar diffuse and total reflection properties, though capturing straight-on is recommended. Our computer vision software automatically finds the QR symbol in the target images and calculates the pixel to reflectance relationship using the known target material reflectance (data download here). The reflectance targets are composed of a felt-like sheet material adhered to a plastic substrate. Care should be taken to ensure the targets are debris-free to produce the best calibration results, often a puff of air is all that is needed to clean them. The target's housing is made of durable, smoothed nylon pl
