Abstract
We describe an IR multi-fibre system we are currently building for UKIRT. SMIRFS (Spectroscopic multiple infrared fibre system) will feed the CGS4 spectrograph, providing it with a multi-object capability in the J, H and K bands. For efficient coupling the inputs and outputs of the fibres are microlensed. Because the telescope is normally focused inside CGS4 for conventional spectroscopy the SMIRFS fibre slit is projected in to CGS4 by a spherical mirror. IR optimised Silica fibres are used for the J and H bands and Zirconium Fluoride fibres are used for the K band.
