Spectralon Diffuse Colour Standards

Labsphere Spectralon Diffuse Colours Standards

Ideal for calibrating spectrophotometers & colorimeters

Labsphere Spectralon diffuse 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 effects 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, with calibrations traceable to NIST. The normal measurement geometry is 8° illumination with hemispherical collection, 360-830nm. 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 greyscale Spectralon standards) in 1.25 and 2.00 inch diameters. Colours available include red, green, blue, yellow, cyan, orange, purple and violet.
