ABSTRACT:
An optical subassembly for in- and/or out-coupling of electromagnetic radiation of a predetermined wavelength, especially IR-radiation, into, and/or out of, a pressure-tight housing. The subassembly includes at least one housing wall section of the pressure-tight housing having at least one opening, wherein, in the opening, mechanical setting means are provided, with which a plug transparent for the electromagnetic radiation is set, wherein the transparent plug has two mutually oppositely lying, base surfaces and a cylindrical lateral surface, and wherein the setting means include as least one setting ring, characterized in the a volume region between at least a first section of the setting ring and at least a section of the cylindrical lateral surface is filled with a pressure-tight, potting compound.
