Problems solved by technology

[0011] The advantages and disadvantages of this method are similar to those of the ultraviolet spectral radiance. The test is simple and the operation is convenient. It only needs to replace the ultraviolet standard detector and the ultraviolet measured detector. The disadvantage is that both the input and output optical systems use two mirrors. , the attenuation of the ultraviolet light signal increases, which reduces the signal-to-noise ratio; in addition, due to the need for sufficient space to install the electronic shutter 7 and filter assembly 8, the focal length of the input optical system must be lengthened, thereby increasing

Abstract

The invention discloses an ultraviolet radiation comprehensive test device and belongs to the field of optical tests and measurements. The device simplifies an input optical system, adds an integrating sphere and an ultraviolet irradiance standard lamp which is arranged on a second mobile platform, and correspondingly integrates the integrating sphere and an electronic shutter on a first mobile platform with the ultraviolet radiance standard lamp and a filtering component on the basis of a conventional spectral responsivity test device; the first mobile platform is in the same direction as a third mobile platform with an ultraviolet standard detector and is vertical to the second mobile platform; and all the standard lamps or the standard detector and lamps to be measured or detectors to be measured are cut into a measurement optical path under control of a data processing system so as to realize measurement and calibration of ultraviolet spectral radiance, spectral radiance illuminance and spectral responsivity. The device solves the problems of resource sharing and cost saving during ultraviolet radiation measurement, and has the characteristics of simple operation and high precision.
