Features
Visualization of UV Radiation
Beam characteristics such as laser mode structure, beam shape, and beam alignment can be observed with the UV Beam Viewer because the optical glass will glow white green when exposed to UV radiation.
Caution should be used for wavelengths less than 300 nm. The glass is still transparent below 300 nm but with higher absorption levels. The absorbed UV light may cause heat or optic may crack.
The UV Beam Viewer is designed to be a viewing tool only which is introduced to an optical system during alignment and troubleshooting. It is not intended to remain in the optical path permanently.
Optical Post Mounting
The 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.
Cleanroom Compatible
These beam viewers are cleanroom-compatible and transmissive at 355 nm.
