Spherical Lenses
Custom Spherical Lenses and Achromats: CNC Ground and Pitch Polished on Optical Glass and Fused Silica
Cimcoop manufactures custom spherical lenses in plano-convex, plano-concave, biconvex, biconcave, and meniscus geometries, plus cemented achromatic doublets and triplets. Components are CNC ground and polished on optical glass (Schott, Ohara) and fused silica, with pitch polishing available for supreme surface form quality. Diameters range from 10 to 150 mm. CNC centering up to 200 mm ensures tight centration tolerances. Applications include cinema prime and zoom lenses, machine vision cameras, medical imaging, and industrial optical instruments.

FAQ
Frequently Asked Questions
What spherical lens types does Cimcoop produce?
Cimcoop produces plano-convex, plano-concave, biconvex, biconcave, and meniscus spherical lenses, plus cemented achromatic doublets and triplets. All geometries are CNC ground and polished on optical glass and fused silica.
What is the difference between CNC polishing and pitch polishing for spherical lenses?
CNC polishing provides consistent, repeatable surface finishes for standard production requirements. Pitch polishing is a traditional craft technique using manually prepared pitch laps that delivers superior surface form accuracy and minimal scatter — used when specifications demand the highest surface quality, such as cinema lens elements.
Does Cimcoop make lenses for cinema applications?
Yes. Cimcoop supplies spherical lens elements and achromats to leading cinema prime and zoom lens manufacturers worldwide. Pitch polishing delivers the surface quality cinema-grade imaging demands, and CNC centering ensures tight centration tolerances across multi-element lens assemblies.
What diameter range does Cimcoop offer for spherical lenses?
Cimcoop produces spherical lenses from 10 to 150 mm in diameter. CNC centering is available up to 200 mm diameter with ±0.01 mm tolerance.
