Custom Plano-Concave Mirrors

Plano-concave mirrors are specialized optical components with one flat (plano) surface and one inward-curved (concave) surface coated with a reflective coating. These mirrors are used for beam focusing, convergence, and specialized optical applications where a converging reflective surface is required. Unlike plano-convex mirrors which diverge light, plano-concave mirrors reflect and converge light from the concave surface.

Our configurator below provides instant online quoting for custom plano-concave mirrors in N-BK7 (H-K9L) and UV Fused Silica (JGS1) substrate materials. You can specify diameter, radius of curvature, edge thickness, and select from many reflective coating options.

If you need materials, coatings, or specifications not available in the configurator (such as custom dielectric coating specifications, wedge angles, mounting holes, or laser damage threshold specifications), please contact us at [email protected] for a custom quote.

Note: It costs about as much to make one custom mirror as it does to make ten, hence the minimum order quantity is 10 pieces. Large price drops occur as volume increases to 100 units.
