Spectral radiance

NATA class of test 1.68.01

ORLAB is NATA accredited for calibration and measurement of light sources for spectral radiance

In the wavelength range 380 to 780 nm

with least uncertainty of

0.7 nm in wavelength

3.3% at 380 nm falling to 1.0% at 555 nm and rising to 1.8% at 780 nm in spectral radiance

These measurements can also be made on-site.

Based on sources calibrated by the National Measurement Institute, Australia and surfaces calibrated by the National Research Council of Canada and the National Physical Laboratory.
