[0002] At present, optical lenses are mainly concentrated in the visible light and infrared bands, and there are fewer products in the ultraviolet band. However, due to the specificity of the surface absorption of ultraviolet spectrum, the details of the surface of the object can be seen more clearly, such as scratches, welding marks or fingerprints on the surface, so it is very suitable for product detection and identification in the industrial production process. The ultraviolet optical lens is mainly composed of a lens module, an ultraviolet filter and an ultraviolet detector image plane. The light reaches the ultraviolet detector image plane after passing through the lens module and the ultraviolet filter.

[0003] UV optical lenses should be precision tested before use to ensure that they maintain excellent performance after use. Currently, precision testing requires timely adjustment of the lens position, such as height and orientation when facing multiple test objects. However, there are the following problems during the test: staff participation in the adjustment is required, the test requirements for a dust-free environment cannot be met, and this is not conducive to accurate testing.
