Product Description

General Introduction:
Raytek silicon carbides, materials engineered specifically for optical systems,are engineered and optimized for applications demanding high stiffness, low mass, and thermal stability. Raytek SiC materials are ideally suited for mirrors and structural components for ground or space-based optical systems. Silicon carbide optical systems are engineered to exhibit low complexity, low mass, and athermal designs, thereby providing enhanced system performance and reliability.
CVD Silicon Carbide is chemical vapor deposited, ultra high purity material used for mirrors or as an optical cladding for UltraSiC material, which is widely used for Optical Applications.
Whether you need one or hundreds of components, Raytek precisely forms, machines, assembles, and tests SiC optical components for a variety of visible and infrared applications in dedicated, quick-turn manufacturing facilities. Raytek high-precision silicon carbide components feature wave front errors and surface roughness equal to or better than traditional substrates. Most typical optical coatings are compatible with our silicon carbide substrates.
Raytek offers expert engineering services including 3D modeling, materials testing, prototyping, and material selection for any optical component specification.
