The invention relates to the field of ultraviolet-vacuum ultraviolet radiation metering and testing, in particular to an ultraviolet light source equalizing device. The ultraviolet light source equalizing device comprises a plurality of diffusers and a driving unit, wherein the diffusers are used for equalizing and focusing incident ultraviolet light in a specific waveband; and the driving unit is used for adjusting corresponding diffusers in an optical path according to testing requirements. Via an embodiment of the ultraviolet light source equalizing device, since the diffusers working within the ultraviolet light waveband range from 110nm to 400nm are utilized to equalize and focus, when a spot light source or an area light source is utilized as the ultraviolet light source, spectral irradiance calibration is guaranteed, good cosine calibration effect can be generated, and signal to noise ratio of a system can be guaranteed.
Description
technical field [0001] The invention relates to the field of measurement and testing of ultraviolet-vacuum ultraviolet radiation, in particular to an ultraviolet light source homogenizing device.
