Diffuse Color Reference Material Set - Calibrated, 4 Discs/Set

This set of Diffuse Reflectance Materials has four calibrated diffuse color disks: orange, purple, cyan, and violet standard. All disks are 2 inches in diameter. Qty. 4

PerkinElmer's Diffuse Color and Neutral Reference Material sets are used to establish the photometric accuracy and linearity of the LAMBDA 850+ and 1050+ spectrometers. These reference materials are supplied with calibration data from 250 to 2500 nm, reported every 50 nm. Sets also included a disk with data for each 1 nm. Reflectance calibration is traceable to NIST® and NPL standards.
