technical field [0001] The invention belongs to the field of optical testing, and mainly relates to an ultraviolet radiation testing device, in particular to an ultraviolet radiation comprehensive testing device capable of measuring three parameters of ultraviolet spectrum radiance, ultraviolet spectrum irradiance and ultraviolet spectrum responsivity. Background technique [0002] UV spectral radiance, UV spectral irradiance and UV spectral responsivity are the three basic parameters in the field of UV radiation testing. The following methods are usually used to test the above parameters respectively. [0003] (1) UV spectrum radiance test device [0004] The test of the radiance of ultraviolet spectrum is generally completed by comparing the standard lamp and the lamp under test.

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 the attenuation of the ultraviolet optical system , so that the measurement accuracy is reduced, and the measurement uncertainty of the current ultraviolet spectral responsivity test device is 15%.

[0012] From the above three test devices, it can be seen that the tests of the three parameters have common parts: UV standard light source, UV monochromator, output optical system, UV Standard detectors and data processing systems, etc., if the application unit establishes three corresponding independent test devices at the same time to complete the measurement of the above three parameters, it will take huge manpower and material resources
