Long-term stability of fibre-optic transmission for multi-object spectroscopy

Sharp, Robert; Brough, Sarah; Cannon, R. D.

Description

We present an analysis of the long-term stability of fibre-optic transmission properties for fibre optics in astronomy. Data from 6 years of operation of the AAOmega multi-object spectrograph at the Anglo-Australian Telescope are presented. We find no evidence for significant degradation in the bulk transmission properties of the 38-m optical fibre train. Significant losses (<20 per cent relative, 4 per cent absolute) are identified and associated with the end termination of the optical fibres...[Show more]
