Abstract
A heating disk is located inside a vacuum chamber between a substrate holder inside the chamber and a lamp outside the chamber. The lamp emits radiation in a wavelength range which passes through a glass plate in the chamber wall but is absorbed by the heating disk, which may consist of graphite. When the disk is heated to 1000.degree. K. it emits radiation in a wavelength range which can be absorbed by a transparent substrate in the holder.
