Abstract
The invention relates to a housing for opto-electronic components, with the semiconductor component being cooled by a cooler which operates in accordance with the Joule-Thomson effect and is in communication with the housing. The gist of the invention is that the non-evacuation housing comprises several sections, with the first section of the housing which is in direct communication with the cooler having a low thermal conductivity and a low thermal capacity, whereas the end section of the housing containing a radiation transmitting window has a high thermal conductivity and a high thermal capacity.
