Method for fabricating a window element sealing a housing

摘要

The method involves forming optically permeable flat support material whose size is sufficient for a number of window elements. One optical coating is provided on at least one of the surfaces, from which coated surface frame shaped sub areas have to be removed which optically enclose the effective surfaces of the window element. A metal layer is placed on the coating free sub areas for the production of the welding joint (15) with the housing.
