Abstract
A transparent composite article may include a first domed surface having a first integral freeform mirror and an opposed second surface having a second integral freeform primary mirror and supporting the first domed surface. The first domed surface and opposed domed surface may include a chemical vapor deposition (CVD) matrix. The CVD matrix may include a silicon carbide material. The CVD matrix may be transparent to visible light. The CVD matrix may include a columnar grain structure.
