UV Negative Best Form Lenses

Special Optics UV Best Form lenses are designed from UV grade fused silica to have the best (or least) aspherical aberration. This is achieved by polishing both sides to different radii optimized for an infinite conjugate source. The lenses are optimized for minimum spot size and can theoretically reach diffraction limited performance for small input beam diameters. Our negative focal length Best Form lenses are asymmetric biconcave.

Custom orders are welcome for other focal lengths, other diameters, individual optical correction, or whatever your needs may be. To receive a custom Best Form lens quote email or call us or complete our line Custom Lens Quote Request Form.
