Abstract

A transmission Dewar cooling chamber having a housing for supporting a semiconductor crystal therein within a temperature controlled environment. The housing has walls made partially of material transmissive to a preselected wavelength in order to allow the passing of a beam of electromagnetic radiation completely through the housing. In addition, mounting means are provided to move the housing in at least two dimensions. Securing the semiconductor crystal in place within the housing is a uniquely designed frame/mount arrangement which aids in establishing the temperature controlled environment for the crystal while also allowing the beam of electromagnetic radiation to pass completely through the crystal.
