Abstract

This paper presents the design of a near IR camera for the 9.2 m Hobby-Eberly Telescope (HET) Low Resolution Spectrograph (LRS), which will cover the wavelength range 0.85 to 1.35 micrometers . The LRS-J, an upgrade to the existing LRS, replaces the optical camera with an f/1 camera optimized for the J-band. The instrument design is strongly motivated by the desire to observe galaxies at 1 < z < 2, where the principal strong spectral features used to measure redshifts are shifted into the J-band. Since we are primarily interested in wavelengths up to 1.35 micrometers , mating the cryogenically cooled camera to the warm LRS spectrograph does not result in enough thermal background emission to compromise its performance. LRS-J represents a rapid and cost-effective way to enable multi-object near-IR spectroscopy on a very large telescope.
