plano-concave lens / spherical / BK7 / optical glass

The Newport BK 7 Precision Plano-Concave Lenses are made to be at par with the extensive requirements of laser electro optic operations. They are made from fine annealed optical glass and then are polished using master test plates for minimum wavefront distortion. The Lenses would have standard diameters from 6.35 mm to 50.8 mm and focal lengths at either uncoated or mutli-layer AR coated.

The UV fused silica precision Plano-Concave lenses are made to be at par with the extensive requirements of laser electro-optic operations. Made with UV grade fused silica, they are then polished in master test plates for minimum wavefront distortion, and these have UV and radiation protection.
