UV Positive Best Form Lenses

Special Optics 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. Our positive focal length lenses Best Form lenses are asymmetric biconvex lenses.

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. Lens Quote Request Form.
