Abstract

A method is provided for producing a housing body for optoelectronic components that are reliable and inexpensive. The method creates a hermetic joint between a metal sleeve and a glass pane by joining together a housing element and a preferably metallic housing arrangement. The housing element and the housing arrangement are brought into contact with a glass solder, before the housing element and housing arrangement are joined. The glass solder is applied as a shapeable material, in particular as a paste. The glass solder is pre-vitrified and has its shape fixed by energy being introduced at least once, in particular as a result of organic constituents being burnt off. After the housing element has been inserted into the housing arrangement, a joint that is hermetic at least in regions, is produced between the glass pane and housing arrangement.
