MSE supplies offers customized Plano Concave Lenses with different materials, dimension, surface qualify, etc.

Plano Concave Lenses, as the name indicates, has a flat surface and a concave surface. The edges are thicker than the center and thus they have a negative focal length. They are usually used to diverse parallel lights and reduce spherical aberration, coma and distortion in different optical systems such as projectors, beam expanders, etc.

MSE Supplies can offer a variant of optical elements, with different material, size, surface quality and coating. Please contact us for customization or bulk orders.
