Press Release
Physical Sciences Inc. (PSI) has recently been awarded a contract from the US Navy to develop a novel machining capability for hardened optical materials.
Physical Sciences Inc. will develop Hard Optical Material Exquisite Quality Electrochemical Surface Tuning (HOME-QuEST) capability for generation of prescribed uncoated optical surfaces in hardened optical materials. Such materials are desirable for their high specific stiffness and chemical resistance. An electrochemical machining (ECM) process will be optimized to provide a 3mm radius, 6mm aperture reflective surface as demonstration, with irregularity better than 500nm and root-mean-square roughness better than 30nm.
