Convex-concave lens

Convex-concave lens is positive meniscus lens, with thicker at the center than at the edge. The convex-concave lenses shorten the focal length and minimize spherical aberration. We offer convex-concave lenses with materials of BK7, JGS1, JGS3, H-ZF1, H-ZF4 and BaK4. Anti-reflection coatings are available, single layer anti-reflection coating and multi-layer anti-reflection coating for wide range of spectrums.
