Aspherical Lenses

An aspheric lens is a single element optical component with one aspheric convex surface and one plano or spherical convex surface. Esco manufactures aspheric lenses from high quality optical crown glass. Each lens is precision molded and felt polished to provide excellent performance in critical condenser applications. Anti-reflection coatings are available and single layer MgF2 is recommended for most applications.

Esco provides fast turnaround on custom aspheric lenses quotations and we accommodate prototype parts or large quantities with a wide range of optical glass. Get in touch with us today to start your order.
