Abstract
An optical component having a plurality of cooling channels in a surface region underlying its effective surface is manufactured by first forming a precursor of the optical component consisting of a main body which carries the effective surface, and a plurality of solid fugitive material cores embedded in the main body at the desired locations of the cooling channels, and then converting the precursor into at least a portion of the optical component by consolidating the main body, and removing the cores from the cooling channels, such as by melting the fugitive material of the cores.
