Optical multiplexer/demultiplexer

Abstract

Abstract 1. Optical multiplexer or demultiplexer consisting of an arrangement one behind the other of a fibre array which contains input and output light wave guides, an imaging optical system as well as a reflecting diffraction grating, characterized by the following features : a) a hollow, cylindrical shaped housing is present, consisting of at least one first housing part (10), at least one second housing part (20) and a joint location (11), which makes a radical displacement and/or rotation of the housing parts (10, 20) each relative to the other possible ; b) the imaging optical system (30) is mounted in the first housing part (10) ; c) the reflecting diffraction grating (50) is rotatably and/or tiltably arranged at that end (13) of the first housing part (10), which is remote from the joint location (11) ; d) the fibre array (60) is mounted in a sleeve (70), which is rotatably and/or axially displaceably and fixably arranged in the second housing part (20).
