Ideal for Calibrating Colorimeters & Spectrophotometers

Labsphere Spectralon® diffuse colour and pastel colour standards are used to calibrate colorimeters and spectrophotometers in the 360-830nm range. Compared with ceramic tiles which are characterised by a glossy surface, the diffuse nature of Spectralon standards simplifies measurements by removing the effect of viewing or illumination geometries. Spectralon is thermally stable, durable, washable and waterproof. The high thermal stability of Spectralon standards also eliminates the need to rigorously control the temperature in the laboratory.

Spectralon colour standards are available calibrated or uncalibrated; calibrations are traceable to NIST. The certificate supplied lists spectral reflectance, tristimulus values, chromaticity coordinates, UCS coordinates and CIELAB and CIELUV values. Standards are available invidually and in sets (together with white and grey scale Spectralon standards) in 1.25 and 2.00 inch diameters. Colours available include red, green, blue, yellow, cyan, orange, purple and violet.
