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

Meniscus Lenses have two curved surfaces: one concave surface and the other convex surface. There are two types of meniscus lenses: positive meniscus lenses and negative meniscus lenses. Positive meniscus lenses have a shorter radius of curvature on the convex surface than the concave surface and negative meniscus lenses have the opposite. Positive meniscus lenses are used to reduce the focal length and spherical aberration reduction while negative meniscus lenses are used to expand the beam. They are widely used in optical system such as cameras, telescopes, 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.
