IR Lenses
Custom Infrared Lenses: Spherical, Aspherical, Diffractive, and Freeform Surfaces in Silicon, Germanium, and ZnS
Cimcoop manufactures custom infrared lenses using single point diamond turning (SPDT) on Moore Nanotech 450 and 250 UPL v.2 systems. Available geometries include spherical, aspherical, diffractive, and freeform surfaces with sub-micron form accuracy. Substrate materials include silicon, germanium, zinc sulfide, calcium fluoride, chalcogenide glass, and IR plastics in diameters from 1 to 200 mm. AR and DLC coatings are applied in-house. Applications span defense, thermal imaging, laser systems, and industrial sensing.
We cut IR lenses on Moore Nanotech 450 and 250 UPL v.2 diamond turning machines. Sub-micron surface form accuracy. Spherical, aspherical, diffractive, and freeform geometries -- whatever your design calls for.
Materials: Si, Ge, ZnS, CaF2, chalcogenide glass, and IR plastics. Diameter range 1 to 200 mm. Defense, thermal imaging, laser, and industrial applications.

FAQ
Frequently Asked Questions
What IR lens geometries can Cimcoop diamond-turn?
Cimcoop diamond-turns spherical, aspherical, diffractive, and freeform IR lens surfaces. The Moore Nanotech 450 UPL v.2 provides 5-axis capability for complex freeform and diffractive surfaces, while the 250 UPL v.2 handles spherical and aspherical geometries at sub-micron accuracy.
What materials does Cimcoop use for infrared lenses?
Cimcoop manufactures IR lenses from silicon (Si), germanium (Ge), zinc sulfide (ZnS/Cleartran), calcium fluoride (CaF₂), chalcogenide glass, and infrared-transmitting plastics. Silicon and germanium are grown in-house.
What is the diameter range for Cimcoop's IR lenses?
Cimcoop produces IR lenses from 1 mm to 200 mm in diameter, covering compact sensor optics through large-aperture thermal imaging and defense systems.
Does Cimcoop apply coatings to IR lenses?
Yes. Cimcoop applies anti-reflection (AR), diamond-like carbon (DLC), and custom thin film coatings to IR lenses in-house. No outsourcing required.
