End effects in optical fibres (2013)
Journal Article
Allington-Smith, J., Dunlop, C., Lemke, U., & Murray, G. (2013). End effects in optical fibres. Monthly Notices of the Royal Astronomical Society, 436(4), 3492-3499. https://doi.org/10.1093/mnras/stt1842

The performance of highly multiplexed spectrographs is limited by focal ratio degradation (FRD) in the optical fibres. It has already been shown that this is caused mainly by processes concentrated around the mounting points at the ends of the fibres... Read More about End effects in optical fibres.
