Paper Abstract

We present the integration of a low dark current extended wavelength (2.3μm cutoff) InGaAs array into the Cornell-Massachusetts Slit Spectrograph (CorMASS) spectrograph. The InGaAs array was fabricated onto a SB- 206 512×512 readout integrated circuit (ROIC) by Goodrich/Sensors Unlimited and subsequently went through a series of laboratory characterization tests at the University of Virginia demonstrating dark current performance of better than 10 e-/s. The InGaAs array is adapted for use with the CorMASS to verify its performance in a proven astronomical instrument, and for eventual deployment to a telescope to test stability and performance.
