Paper Abstract

This paper describes an image slicer based on a modified version of the Bowen-Walraven slicer. The new design is called Confocal Image Slicer, and delivers a large number of slices, all in focus. This allows the slicing of a wider area of the seeing disk, to the benefit of very high resolution spectrographs like the Ultra-High-Resolution Facility, where the slicer gives access to stars up to 3 magnitudes fainter than the limit imposed by a narrow slit for the same resolution and signal to noise ratio. The basic principle and design philosophy of the confocal image slicer are presented, together with a description of the development of a prototype and a final version now fully commissioned at the Anglo-Australian telescope. Some astrophysical results are also included.
