Aspherical lenses are designed to reduce spherical aberration. Complex multi-lens systems designed for compensation of spherical aberration can often be replaced with a single aspheric lense. We offer ex-stock delivery of CNC polished precision plano-convex aspherical lenses made of N-BK7, high refractive index N-LAH64 glass or UVFS.

 

  • Material: N-BK7, S-LAH64 or UVFS
  • Can be supplied with AR coatings under request

We can produce aspherical lenses of custom design using your drawings or specifications in our CNC lens polishing facility. Lenses can be supplied with anti-reflection coatings under request.
