Abstract
Multi-object fibre optic feeds are being prepared for use with the Cassegrain spectrographs of the La Palma Observatory 2.5m Isaac Newton Telescope and 4.2m William Herschel Telescope. The techniques used for terminating and preparing the fibres are described. In order to maintain high efficiency when feeding f/15 and f/11 spectrographs with fibres, microlenses have been used. The preparation and setting up of a microlensed fibre system to feed the f/15 spectrograph of the INT from the f/3.3 prime focus is described. The performance of this system is demonstrated in the laboratory and details are given of the system under construction for the WHT.
