Irradiance

Spectrophotometers

NATA class of test 1.69.08

ORLAB is NATA accredited for calibration of spectrophotometers

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

These calibrations can also be carried out on-site

Based on filters calibrated by the National Research Council of Canada.
