Abstract

This paper describes the properties of CVD diamond material, which can be fabricated as domes up to 70 mm in diameter, by plasma assisted CVD (PACVD). Domes of "near-net-shape" are reported, showing that good thickness and crystal morphology uniformity are obtained during the synthesis stage. Preliminary results on the processing of "as-grown" CVD diamond domes and the tolerances achieved (in the correct spherical shape) for IR optical applications are presented.

Finally, the characterisation of IR and optical properties and mechanical strength of CVD diamond planar samples is reported.
