Abstract:

We describe a concept for a new imaging spectrograph operating in the mid-wave and long-wave infrared. The instrument is proposed as an upgrade to The Aerospace Corporation’s Broadband Array Spectrograph System (BASS), a 3-13 micron sensor currently in use on the Advanced Electro-Optical System (AEOS) 3.67 meter telescope. The primary tasks of the instrument would be to generate precise spectrophotometry of stars, and to characterize resident space objects. The core of the design features two ultra compact spectrographic modules, each utilizing a concentric Dyson lens and concave diffraction grating. We will describe the considerable advantages that result for this design as well as the implementation of the instrument on the AEOS telescope and similar facilities.
