Abstract
Apparatus for monitoring the output of an optical system. The apparatus comprises first and second fibre optic sections, a reflective coating, and a detector. The first fibre optic section has a first cladding and a first core, and is configured to receive light from the optical system at one end and has at the other end a first angled, polished face. The second fibre optic section has a second cladding and a second core, and has at one end a second angled, polished face. The first and second fibre optic sections are arranged such that the first and second angled, polished faces are substantially parallel and adjacent and the first and second cores are substantially aligned. The reflective coating is applied to the first or second angled, polished face, and is configured to reflect a portion of light transmitted through the first core. The detector is arranged to receive the reflected light.
