PROVIDENCE, R.I., Oct. 17, 2012 — Polarizing beamsplitters and beam combiners for CO2
lasers from 100 W up are being introduced by Laser Research Optics.
beamsplitters facilitate power measurements and beam alignment by reflecting a percentage of the beam, typically 50%, which covers all polarizations. The beam combiners, which combine 10.6- and 0.633-µm (HeNe) wavelengths, permit alignment and focusing by providing a visual light beam.
Designed for engraving, marking and scribing lasers, the devices are made from ZnSe with various coatings to achieve their polarization states. The beamsplitters permit up to 50% transmission and ±3% reflectance, while the beam combiners allow 98.7% light transmission. Both are offered in ¾- to 3-in. outer diameter sizes.
