A New Form of Spectrograph Camera
Abstract
Various causes of loss of spectrograph efficiency, which arise in multi-object fibre-fed spectroscopy and in the instrumentation of very large telescopes, are discussed. A new form of spectrograph camera is described which provides some mitigation. A numerical example is given, illustrating, in particular, reduction of central obstruction.
