Replicated Hybrid/Composite Mirror Technologies
Agency / Branch:
DOD / USAF
This Phase I SBIR program is focused on developing engineered materials for a replicated hybrid/composite mirror that can operate in the visible optics range at ambient air or space condition and that has an areal density <7 kg/m2. The proposed replicated mirror system is based on the nano-laminates of SiC and Si3N4. The underlying concept of using SiC and Si3N4 is to construct the mirror, attachment bonding material, and SiC substructure in such a way that they all possess very close thermal expansion coefficients. The replicated SiC/Si3N4 nano-laminate mirror surface will be characterized optically to meet the requirements of the surface figure error and surface roughness (63 nm RMS and 2 nm RMS, respectively).At the end of the program, 10 cm flat replicated mirror with required optical quality will be delivered.
