Spherical

We fabricate spherical lenses from 0.250"Ø to 8"Ø using materials such
as BK-7 to Excimer Grade Fused Silica. Surface finishes are usually 1/10l
spherical and/or 1/10l flat with 20/10 or better scratch & dig.

Cylindrical

Plano/Concave & Plano/Convex cylinder lenses with dimensions of 2" Ø ,
2" x 2" square, and 3" x 3" square are fabricated on a daily basis. The
material used is primarily Suprasil® 2. Standard tolerances are 1/4l with
40/20 scratch and dig, but tighter tolerances can be met.

We stock a number of different cylindrical and spherical lenses, and we
would be happy to quote on any custom lens requirement.
