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 UV fused silica.
We can produce aspherical lenses of custom design using your drawings or specifications in our CNC lens polishing facility.
- Material: UVFS, N-BK7, S-LAH64 or other glasses
- Diameter: from 10 mm to 120 mm
- Can be supplied with AR coatings under request
