UV spectral irradiance

The relative and absolute spectral irradiance of deuterium lamps is measured over the wavelength range 200 nm to 400 nm.

Measurements are carried out on our UV Spectroradiometer facility, which utilises a UV monochromator system with a PMT detector. Calibrations are carried out against a series of NPL standards traceable to the NPL2003 absolute irradiance/radiance scale.

Calibrations of either relative or absolute irradiance can be made at variable intervals depending on your requirements.
