Fused Silica Bi-Concave Lens, 50.8 mm, -200 mm EFL, 1064 nm

The SBC046AR.33 Bi-Concave Lens is a 1064 nm antireflection coated, 50.8 mm diameter, UV grade fused silica bi-concave lens with an effective focal length of -200 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.
