Making High Performing Silicon Carbide Accessible for Space Optics
Reduce costs by 30% to 65% with Entegris CVC SiC Mirrors with Silicon Cladding
Entegris is redefining what’s possible in space optics with new and affordable silicon (Si) cladding solutions. Our latest technology combines our unique chemical vapor converted silicon carbide with a cost-enabling silicon cladding for easy, low-cost polishing. Our mirrors can be quickly polished using slurries or single point diamond turning on both flat and curved mirrors reducing your cost of ownership.
By uniting the mechanical strength of SiC with the optical finish of silicon, our advanced optics solutions empower system designers to push the boundaries of resolution, thermal performance, and mass efficiency while slashing costs in half.
Partner with us to enhance your satellite designs with superior performance and affordability.

The Entegris Chemical Vapor Conversion Process
Entegris’ innovative chemical vapor conversion process begins with machining the component from a specialized type of graphite. This graphite can be rapidly and efficiently machined using conventional multi-axis CNC machines, allowing for complex designs and lightweight structures. Once the desired shape is achieved, the graphite is fully converted into SiC, resulting in minimal and predictable dimensional changes. After conversion to SiC, the optical surface is cladded with a premium silicon using a novel process, and is easily polished or diamond turned to a high finish. This fabrication process not only streamlines production but also enhances the performance of the final optical components.
The Future of Silicon Carbide Manufacturing: Innovations and Techniques
Silicon carbide (SiC) is renowned for its superior mechanical and thermal properties, making it an ideal candidate for high-performance optical systems. However, its adoption has been limited due to challenges related to finding reliable and cost-effective manufacturing techniques.
