Optical fiber feedthrough for a vacuum chamber

Abstract

Disclosed is an optical fiber feedthrough (10) configured to feed through optical fibers (1) between an interior and exterior of evacuable vacuum chamber (30). The feedthrough includes at least one mounting flange (11a, 11b) configured for pressure-tight fastening to vacuum chamber and includes passage openings (12a, 12b) configured for pressure-tightly receiving a respective optical fiber. The passage openings are each provided with a sealing receptacle (13a, 13b) and a sealing element (14a, 14b) arranged therein for pressure-tightly receiving the respective optical fiber. A compression device (15a, 15b) is connected to each mounting flange, which is configured to compress the respective sealing elements axially along the respective passage openings. Also disclosed is an optical fiber assembly (20) including the feedthrough and optical fibers, and a method for passing a plurality of optical fibers between an interior and exterior of an evacuable vacuum chamber using the aforementioned feedthrough.
