Custom Double-Concave Lenses

Double-concave lenses have two inward-curved surfaces, providing stronger diverging power than plano-concave lenses. They are ideal for beam expansion, diverging systems, and optical instrumentation where negative optical power is required.

Our configurator below provides instant online quoting for custom double-concave lenses in N-BK7 (H-K9L) and UV Fused Silica (JGS1) materials. You can specify diameter, radii of curvature for both surfaces (allowing symmetric or asymmetric designs), edge thickness, and select optional AR coatings.

If you need materials, coatings, or specifications not available in the configurator, please contact us at [email protected] for a custom quote.

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