LASER DEBRIS SHIELDS MADE FROM SAPPHIRE FOR LONGER SERVICE

A line of sapphire laser debris shields that can withstand steel splatter, flash, and debris to reduce focus shift and maintain the laser beam quality has been introduced by Laser Research Optics of Providence, Rhode Island.

Laser Research Sapphire Debris Shields feature A/R coatings on both sides to provide transmission of > 99.5% @ 1.06 microns with > 80% @ 650-670 nm. Far more robust than fused silica protection glasses, they can withstand steel splatter, flash, and debris to reduce focus shift and prevent the deterioration beam quality while extending the service life.

Reducing the number of required lens changes, Laser Research Sapphire Debris Shields have lower bulk absorption with about 30X higher thermal conductivity. Available in 0.5” and 2.0” sizes, these laser debris shields feature Mohs 9 hardness which is second only to diamond and 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.
