Laser Debris Shields Protect Optical Components from Steel Slag and Splatter

A line of sapphire laser debris shields for use on high power lasers to protect the optical components from steel slag and splatter has been introduced by Laser Research Optics of Providence, Rhode Island.

Laser Research Sapphire Cover Glass for fiber lasers prevents the laser's optical components from damage caused by slag and splatter and are much more robust than fused silica debris shields. Featuring Mohs 9 hardness, these sapphire laser debris shields reduce the number of required lens changes on lasers from 4 kW and above and extend their service life.

Second only to diamond in terms of hardness, Laser Research Sapphire Cover Glass reduces focus shift and the deterioration of beam quality.

The glass on the shields has an A/R coating on both sides to provide transmission of > 99.5% @ 1.06 microns with > 80% @ 650-670 nm. These laser debris shields have a 10-5 scratch-dig finish and 1/4 wave transmitted wavefront.
