MSE PRO™ Laser Grade Fused Silica Plano-Concave Lenses with AR Coating @450-800nm, Ø1/2"
MSE supplies offers Ø1/2" Laser Grade Fused Silica Plano-Concave Lenses with VIS AR Coating. This series laser grade plano-concave lenses are designed for high energy laser applications. The lenses made of high-quality fused silica material, respectively coated with visible light multilayer anti-reflection coating (450-800nm). The product has a high damage threshold (7.5J/cm2). Fused silica glass has better uniformity and lower thermal expansion coefficient than BK7 glass, and has superior imaging and damage resistance properties in the ultraviolet to near-infrared region.
MSE Supplies can offer a variety of optical elements, with different focal length and coating options. Please contact us for customization or bulk orders.
