Bi-Concave Lens, Fused Silica, 25.4 mm, -150 mm EFL, 245-440 nm
Model: SBC025AR.10
Product Series Overview
UV Coated UVFS Bi-Concave LensesThe 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.
