Abstract
An optical bench (10) includes a pair of end plates (12, 14) rigidly interconnected by a plurality of tubular connecting members (16). The connecting members (16) are formed by chemically vapor-depositing silicon carbide on a mandrel (17) and result in high-precision surface finishes which do not require subsequent machining or surface treatment. The end plates (12, 14) are formed by casting a reaction-bonded silicon carbide into near-final shape. Socket holes (18) are formed in the end plates (12, 14) to receive the connecting members (16) which are secured to the end plates (12, 14) by brazing.
