Technical Information
 
 

Labsphere is one of the few U.S. suppliers of specular standards for the calibration of spectrophotometers used for measuring highly specular materials. The specular standards are UV enhanced (magnesium fluoride overcoating) and cover the spectral range from the UV to the NIR. The standards are available in 1 and 2-inch diameter or square (1 x 1 and 2 x 2 inch) sizes.

A hardcopy printout of the spectral calibration data (50 nm resolution) is supplied with each standard; higher resolution spectral calibration data (5 nm resolution) are available on disk as either ASCII files or in Excel format. Calibrations are performed at 8 incidence using an integrating sphere. Calibrations at other incidence angles are available, per customer request. Specular standards are traceable to standards at the National Institute of Standards and Technology (NIST), and the National Research Council Canada.

In addition to providing calibrated specular standards, Labsphere also provides a calibration service for specular materials. Please contact the Technical Sales Department for further information.
