Newport Corporation has introduced a UV beam viewer, the UVU-2A.
By placing this optically clear device into the path of a UV laser, beam characteristics such as laser mode structure, beam shape, and beam alignment can be easily observed, the company says. The optical glass of the clean-room-compatible UV beam viewer will glow white green when exposed to UV radiation.
Newport’s UV beam viewer features a useful wavelength range of 193 – 355 nm and is suited to the wavelengths of Excimer lasers commonly used in semiconductor manufacturing, micromachining applications, as well as in eye surgery.
The robust UVU-2A housing provides threaded #8-32 and M4 holes to enable use as a wand or to be mounted on a bench using Newport’s standard posts. With its 5 mm profile, the UV beam viewer can be easily inserted into even the tightest optical setups. The large, 48.3 mm, clear aperture allows the user to readily capture the beam on the optic.
