Scientific paper

We describe a design for a compact cooled spectrograph which incorporates two cameras and two collimators to achieve high throughput from 0.8 to 2.5 micrometers. The spectrograph utilizes multiple Near Infrared Camera and Multi-Object Spectrometer 3 (NICMOS 3) arrays, specially mounted to minimize their separation in the spectral dimension. This accommodates the broad wavelength range while providing extensive coverage in the spatial dimension.
