The SBC025AR.10 Bi-Concave Lens is an 245 to 440 nm antireflection coated, 25.4 mm diameter, UV grade fused silica bi-concave lens with an effective focal length of -150 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's UV grade fused silica precision bi-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.


SBC025AR。10双凹透镜为245 ~ 440nm防反射涂层,直径25.4 mm,紫外级熔融石英双凹透镜,有效焦距- 150mm。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级熔融石英精密双凹透镜采用主试板抛光,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。
