Abstract

The UCSD IR astronomy group has built an array grating spectrophotometer suitable for ground based 10 pm astronomical spectroscopy. The spectrophotometer employs a 128 element linear Si:Bi array with on-focal-plane analog multiplexers and discrete integrating capacitors. The system is designed to give thermal photon background limited noise performance and readout rates rapid enough to allow readout synchronous with standard IR chopping (roughly 30 Hz, corresponding to data rates of approximately 5 x 104 bits per second).
