Cylindrical lenses
We can help you design, develop and manufacture high precision cylindrical lenses. The shapes include conventional plane-convex, plane-concave, convex and concave, bi-convex, bi-concave cylindrical lens and unconventional hyperboloid cylindrical lens and tire mirrors.
Cylindrical lenses have a focus line instead of focal point due to their geometry and are widely used in various designs.
Material
We are experienced in working with a vast range of materials, including:
- Common Glass (Schott, Ohara, Hoya, CDGM)
- Fused Silica
