Method for producing a polycrystalline diamond element and element produced according to said method

摘要

A method for producing a preferably optical polycrystalline diamond element is provided. A substrate having a surface which is complementary to said element is molded and is coated by means of diamond deposition. The diamond element is then removed from the mold. The diamond element is finished either before or after being removed from the mold. The substrate is machine cut in order to form the complementary molded product having at least one spherical surface, whereupon it is covered with a polycrystalline diamond by chemical vapor deposition (CVD).
