Description

Technical Field

[0001] The utility model relates to the technical field of radiation-resistant lens testing, and more specifically, to a radiation-resistant lens testing device. Background Art

[0002] Radiation-resistant lens is a lens used in nuclear power plants. It can withstand 10e6Gy of radiation and is used in nuclear industry, nuclear power plants, high-radioactivity laboratories, irradiation stations, chemical defense vehicles and other medium and high-radioactivity application fields. During the production of radiation-resistant lenses, testing equipment is required to test the radiation resistance of the radiation-resistant lenses.

[0003] In the prior art, different test processes require different optical mask areas, and in general test equipment, the radiation lamp beads can only change the light intensity, but cannot change the radiation irradiation area. When testing an optical mask with a smaller area, the radiation resistance performance test time is relatively long, and the light irradiated by the lamp beads generates heat dissipation, which makes the radiation irradiation area large and the effective test irradiation area small, thus resulting in energy waste;

[0004] The Chinese patent with patent application number CN202320023038.5 discloses a device for testing the radiation resistance of photomask substrates. The device rotates the rotating rod, so that the rotating rod drives the threaded barrel to rotate through the limit groove, so that the threaded barrel rotates on the internal thread of the threaded sleeve, and the threaded barrel drives the lamp beads to move horizontally, so that the relative position between the lamp beads and the lampshade changes. The lampshade is a truncated cone-shaped reflector cover, and the arc of the lampshade at the small mouth is large, and the arc at the large mouth is small, so that the lampshade reflects the light of the lamp beads from sparse to dense, and the irradiation area changes from large to small, so as to achieve the effect of adjusting the irradiation area of ​​the lamp beads of the irradiation lamp.
