By placing this optically clear device into the optical path of a UV laser, beam characteristics such as laser mode structure, beam shape, and beam alignment can be observed because the optical glass will glow green when exposed to UV radiation. Unlike conventional ceramic beam viewers, Newport's UV beam viewer is suitable for high power applications, is cleanroom-compatible, and it is transmissive (resulting in much easier beam alignment). The UVU-2 housing provides threaded #8-32 and M4 holes to enable use as a "wand" or to be fixed on a bench using our standard posts. |
