Abstract
A process for converting precursor objects into a unitary ceramic object produces, for example, a ceramic, optical scan mirror that is formed from at least two pieces. An optical section has at least one optical surface and at least one attachment surface, and a support section has at least one attachment surface and preferably has a mounting area. The optical and support sections are formed as separate pieces from a precursor material, such as graphite, such that a selected support section can receive any of a plurality of optical sections having different sizes, shapes, or orientations. To form the mirror, the attachment surfaces are placed adjacent each other, and then the sections are converted simultaneously to a ceramic material, such as silicon carbide, to form a monolithic scan mirror.
