Fiber laser optics sapphire windows

Providence, RI - Laser Research Optics has introduced fiber laser sapphire windows for 1 micron optics. The windows act as debris shield replacements with Moh 9 hardness and reduce frequency of required lens changes. Available sizes range from 1 to 2 in. and withstand steel splatter, flash, and debris. Featuring 10-5 scratch-dig finish, 1/4 wave flatness, and A/R coatings on both sides, windows provide >99.5% transmission at 1.07 microns with >90% at 650-670 nm. Fused silica UV grade windows coated on one or two sides are also offered.

A new series of protective sapphire windows for 1 micron optics that offer superior durability to zinc-sulfide and fused silica lenses is being introduced by Laser Research Optics of Providence, Rhode Island.

Laser Research Fiber Laser Sapphire Windows feature Moh 9 hardness, which is second only to diamond, making them more durable and scratch-resistant than zinc-sulfide and fused silica windows.
