Plano-Concave Spherical Lenses

Plano-Concave Spherical Lenses are available in both Laser Quality and Analytical Quality polish designated as LQ (Laser Quality) and AQ (Analytical Quality).

Plano-Concave Spherical Lenses are available in UV Grade Fused Silica (FS) & BK7 Glass materials. Plano-Concave Spherical Lenses have one flat (plano) surface and one spherical surface curved inward (concave) to diverge the transmitted rays from an object, thus forming a real or virtual image of that object.. Plano-Concave Spherical Lenses are typically used to diverge collimated incident light. Often used to expand light or increase focal lengths in an optical system. These lenses have negative Effective Focal Lengths.
