VIS Positive
Best Form Lenses
Special Optics Best Form lenses are designed from 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
