COATINGS AND SPLITTERS
Feb 2004Alpine Research OpticsRequest Info
Dichroic coatings and beamsplitters for separating the various harmonics of solid-state lasers are targeted at laser manufacturers and systems integrators for micromachining and semiconductor metrology applications. From Alpine Research Optics, the standard line includes short- and long-wave pass optics for 1064-, 532, 355- and 266-nm operation. The flat optics are for first-surface operation at 0 and 45° incidence; they have an AR coating on the second surface. The standard beamsplitters measure up to 3 in. and have λ/10 flatness. The UV beamsplitters are fabricated on UV fused silica substrates, and the 1064- and 532-nm ones use optical-grade fused silica substrates.
