Silicon Optics for High-Power CO₂ Laser Systems: Lenses, Windows, and Substrates
Cimcoop manufactures silicon substrates and finished optics for CO₂ laser systems operating at 10.6 μm. Products include focusing lenses, protective windows, output couplers, and raw silicon blanks for laser cutting, marking, engraving, and medical laser applications. Silicon crystals are grown in-house with controlled resistivity and transmission, providing full material control from ingot to finished optic. Available as raw blanks, semi-finished substrates, or fully finished AR-coated optics.
In-house grown Silicon. Diamond-turned and polished. Built for multi-kilowatt CO₂ laser systems that cut, engrave, and heal.
Industry Focus
CO2 Lasers
CO2 lasers operate at 10.6 microns. Silicon is the ideal transmissive material at that wavelength. We manufacture Silicon substrates and finished optics -- lenses, windows, and output couplers -- built for the demands of high-power CO2 laser cutting, marking, engraving, and medical laser systems.
We grow our own Silicon crystals. Full control over material quality, resistivity, and transmission from the ingot stage. Substrates are sliced, ground, and prepared as precision blanks, then diamond-turned or CNC-polished into finished lenses and windows with the surface quality laser beam delivery requires.
Raw blanks for your own fabrication, semi-finished substrates, or fully finished and coated optics ready for installation. We supply CO2 laser OEMs and aftermarket distributors worldwide. Whatever level of processing fits your workflow, we build it.

FAQ
Frequently Asked Questions
Why is silicon used for CO₂ laser optics?
Silicon has excellent transmission at the CO₂ laser wavelength (10.6 μm), high thermal conductivity, and good mechanical strength, making it the ideal transmissive material for high-power CO₂ laser beam delivery systems.
Does Cimcoop grow its own silicon for CO₂ laser optics?
Yes. Cimcoop grows single-crystal silicon in-house with controlled resistivity, oxygen content, and transmission characteristics. This provides laser-grade material quality and full traceability from the ingot stage.
Can Cimcoop supply raw silicon blanks or only finished optics?
Both. Cimcoop supplies raw crystal-grown silicon blanks for customers who fabricate their own optics, semi-finished substrates with controlled dimensions, and fully finished diamond-turned or polished optics with AR coatings ready for installation.
