The SPX040AR.14 Fused Silica Plano-Convex Lens is a 430 to 700 nm anti-reflection coated, 2 inch (50.8 mm) diameter, fused silica plano-convex lens with an effective focal length of 75.6 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's UV grade fused silica precision plano-convex lenses are polished to tight tolerances using master test plates to ensure minimum wavefront distortion. UV grade fused silica will not fluoresce under UV light and is resistant to radiation. And for high-energy applications, the extreme purity of fused silica eliminates microscopic defect sites that could lead to laser damage.



SPX040AR。14 .熔融硅平凸透镜为430 ~ 700 nm的防反射涂层，直径2英寸(50.8 mm)，有效焦距75.6 mm。它是为满足激光电光应用的要求而设计的。纽波特公司的UV级熔融石英精密平凸透镜采用主试板抛光至严格公差，以确保最小的波前畸变。紫外级熔融石英在紫外光下不会发出荧光，并且抗辐射。对于高能应用，熔融二氧化硅的极高纯度消除了可能导致激光损伤的微观缺陷位点。
