Abstract
Instruments and methods are disclosed which measure absolute energy and irradiance of UV light sources. The response curves of exemplary optical stacks of the radiometry instruments are substantially rectangular with steep transitions at the cutoff frequencies. Angle of incidence (AOI) control in combination with one or more interference filters in the optical stack enable the full optical stack to produce repeatable and accurate measurements. Inverse response filters are disclosed for leveling optical stack response.
