Spectrophotometers

NATA class of test 1.69.04

ORLAB is NATA accredited for calibration of spectrophotometers in the geometries of specular included, specular excluded and 0°/45°.

with least uncertainties of measurement in the ultraviolet-visible spectrum of -
0.3nm in wavelength
0.1% minimum detectable stray light
0.9% reflectance

These calibrations can also be carried out on-site

Based on white tiles calibrated by the National Research Council of Canada and coloured tiles calibrated by the National Physical Laboratory, UK.
