Newport Corp. introduces its ultraviolet 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 optical glass of the cleanroom-compatible UV beam viewer will glow white green when exposed to UV radiation.
Newport’s UV beam viewer features a wavelength range of 193 to 355 nm and is intended for the wavelengths of Excimer lasers commonly used in semiconductor manufacturing and micromachining applications, as well as in eye surgery.
The 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 thin 5 mm profile, the UV beam viewer can be inserted into tight optical setups. The large, 48.3 mm, clear aperture allows the user to readily capture the beam on the optic.
