GCL-L03 Laser Grade Plano-Concave Lenses
GCL-L03 Laser Grade Plano-Concave Lenses
GCL-L03 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) and near-infrared multilayer anti-reflection coating (800-1100nm). 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.
