Diamond optics
We create artificial CVD diamond production technologies for various applications. One of the regular products of the Company is high-quality optical windows.
The high damage threshold of the CVD diamonds is achieved with the combination of the record-breakingly high heat conductivity, low heat expansion, relatively low optical absorption coefficient, and high mechanical strength.
