SAPPHIRE DEBRIS SHIELDS REDUCE DETERIORATION OF BEAM QUALITY

A line of laser debris shields for lasers from 4 kW up that can withstand steel splatter, flash, and debris better than fused silica has been introduced by Laser Research Optics of Providence, Rhode Island.

Laser Research Sapphire Debris Shields feature Mohs 9 hardness, which is second only to diamond, and can withstand steel splatter, flash, and debris to reduce focus shift and the deterioration of beam quality. Available in 0.5” and 2.0” sizes, they have lower bulk absorption with about 30 times higher thermal conductivity than fused silica protection glasses.

Extending service life and the required number of lens changes, Laser Research Sapphire Debris Shields have A/R coatings 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.

Laser Research Sapphire Debris Shields are priced according to size and quantity. Price quotations are available upon request.
