Description
Summary:© SPIE. Downloading of the abstract is permitted for personal use only. We present the InGaAs detector system of the Wide-Field Infrared Transient Explorer (WINTER), a new infrared instrument operating on a 1 meter robotic telescope at the Palomar Observatory. These commercially produced sensors are cooled to -50 °C by a thermo-electric cooler integrated into a room temperature package. These warm InGaAs sensors represent a dramatic reduction in cost and complexity over HgCdTe systems and achieve sky background-limited performance across our science bands for exposures greater than a few seconds. We present the design and implementation of the WINTER detector system and readout electronics.
