The SPC013 Fused Silica Plano-Concave Lens is an uncoated 12.7 mm diameter fused silica plano-concave lens with an effective focal length of -25 mm. It is designed to meet the demanding requirements of laser electro-optic applications, Newport's UV grade fused silica precision plano-concave 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.


SPC013型熔融石英平凹透镜是一种直径12.7 mm的无涂层熔融石英平凹透镜，有效焦距为-25 mm。为满足激光电光应用的要求，纽波特公司的UV级熔融石英精密平凹透镜采用主试片抛光至严格公差，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。
