Laser Research Optics’ sapphire laser debris shields protect fiber laser optical components

Laser Research Optics offers sapphire laser debris shields to prevent fiber lasers’ optical components from damage caused by slag and splatter. Featuring Mohs 9 hardness, the debris shields reduce the number of required lens changes on lasers from 4 kW and above, says the company.

With A/R coatings on both sides, the debris shields provide transmission of more than 99.5% at 1.06 µm and more than 80% at 650 to 670 nm.
