Abstract
A glass diffuser is fabricated by first producing a metal shim submaster or other high temperature resistant diffuser having a surface relief structure on one surface. A glass substrate material is heated to a suitable temperature and at least one exposed surface is thereby softened to a desired degree. The submaster diffuser, and particularly the surface relief structure, is then placed in contact with the exposed and softened glass substrate material in order to replicate the surface relief structure in the glass material. The submaster diffuser and the glass substrate are separated and then the glass is allowed to cool to form a glass diffuser.
