Advanced Systems
AOA Xinetics’ expansion of its silicon carbide facility now means that lightweight optics and precision structures in the 1.5-meter class are possible. CERAFORM Silicon Carbide provides a superior combination of material properties and forming technologies. High specific stiffness, lightweight designs, and low inertia, previously possible only in beryllium, are now possible in a material which exhibits the thermal performance of the low expansion glasses.
Recent thermal strain data taken from 5 to 300 Kelvin show CERAFORM Silicon Carbide to be thermally stable to 20-ppb. Recent processing breakthroughs attained the fabrication of meter class mirrors with areal densities of 5-kg/m2. CERAFORM Silicon Carbide can be directly polished to <10-Angstroms rms surface finish and with figures better than 1/10 PV. AOA Xinetics also uses the CERAFORM casting process for complex mechanical structures.
