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.We have some great aspherical lens blogposts.
