Custom Plano-Convex Mirrors

Plano-convex mirrors are specialized optical components with one flat (plano) surface and one outward-curved (convex) surface coated with a reflective coating. These mirrors are used for beam expansion, divergence, and specialized optical applications where a curved reflective surface is required. Unlike plano-convex lenses which focus light, plano-convex mirrors reflect and diverge light from the convex surface.

Our configurator below provides instant online quoting for custom plano-convex 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 protected vs. unprotected coatings, 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.
