Paper Abstract

We have designed a compact all-reflective near infrared (1 - 2.5 micrometer) long slit spectrograph and imager (CAIRS) for the UK infrared telescope (UKIRT). CAIRS will provide a comprehensive spectroscopic and imaging capability in the near infrared. In spectrograph mode, it uses one slit or two slits for use with image slicers so that it can be used to provide two-dimensional spectroscopy over an extended field. Different gratings can be used in order to reach resolving powers up to 5000. As the instrument uses only mirrors, there is no chromatic aberration and all primary aberrations are almost completely eliminated over a large field of view.
