A line of sapphire windows designed for larger industrial cutting lasers from 4 kW and above that are highly durable replacements for debris shields are available from Laser Research Optics.

Laser Research Fiber Laser Sapphire Windows are capable of withstanding steel splatter, flash, and debris; making them a longer lasting replacement for debris shields on 1064 nm industrial cutting lasers from 4 kW and above. Reducing the typical number of lens changes, these fiber laser sapphire windows feature Moh 9 hardness which is second only to diamond.

Available in 1" to 2" sizes, Laser Research Fiber Laser Sapphire Windows have a 10-5 scratch-dig finish, ¼ wave flatness, A/R coatings on both sides, and provide > 99.5 percent transmission @ 1.07┬Ám, with > 90 percent @ 650-670 nm. Fused silica UV grade windows coated on one or two sides are also offered.

  • flash

    flash

    Thin web or film of metal on a casting that occurs at die partings and around air vents and movable cores. This excess metal is due to necessary working and operating clearances in a die. Flash also is the excess material squeezed out of the cavity as a compression mold closes or as pressure is applied to the cavity.

  • hardness

    hardness

    Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
