Abstract: A system and method for depositing a CVD diamond coating on a non-planar surface of an object is provided. The system includes a deflector (120) having a deflecting surface (122) which resists diamond coating by the diamond forming reagents produced by the system and which is adapted to withstand the relatively high deposition temperatures is provided. The deflector is positioned substantially axially with an axis of the distribution head (102) of the CVD engine. The deflector (120) is preferably generally wedge-shaped or conical and coupled to a motor (112) which is adapted to rotate the deflector at a relatively high speed. A mandrel (104) may be positioned about or to one side of the deflector. The deflector (120) is oriented with respect to the distribution head (102) and the mandrel (104) such that a jet exiting the distribution head is deflected by the deflector onto a surface of an object (110) positioned on the mandrel.
