Abstract
We describe the specifications and design of a 1 - 5 micrometer camera (IRC-UNSW) being built at the School of Physics, University of New South Wales, for use on the 4-m Anglo- Australian Telescope (AAT) and the 2.3-m telescope of the Australian National University. The camera design uses three off-axis mirrors, allowing it to correct the off-axis aberrations in the telescopes themselves, and to obtain images with FWHM blur circles of 10 micrometer over a wide field-of-view (4.5 by 4.5 arcmin on the AAT, 5.8 by 5.8 on the 2.3-m). The camera accepts a collimated beam and can be used with an external Fabry-Perot etalon. We have fully characterized the performance of the camera with respect to misalignment and manufacturing errors. A thermal model has allowed us to calculate cool-down times, cryogen usage, and distortion due to small temperature differences in the optical system.
