Frequently Asked Questions

Which lens types can you make?
Plano-convex, plano-concave, double-convex, double-concave, meniscus, achromatic, aspheric and cylindrical lenses, all to custom specifications.
What centration accuracy is possible?
Centration down to 30 arcsec, with diameter and thickness tolerances down to ±0.01 mm.
When should I choose an achromatic or aspheric lens?
An achromat reduces chromatic aberration for broadband or multi-wavelength light. An asphere reduces spherical aberration, giving a tighter focus with fewer elements.
Do you offer IR lenses?
Yes. Lenses can be made in CaF2, Si, ZnS or ZnSe for mid- and long-wave IR, with matching AR coatings.
What should I include in a quote request?
Lens type, material, diameter, focal length or radii, center thickness, tolerances, coating band and quantity, or a drawing.
