Abstract
The Leonardo (formerly Selex ES) SAPHIRA 320 X 256 @24μm pitch L-APD MOVPE HgCdTe array is now generally accepted as the sensor of choice for near infrared (NIR – 0.8 to 2.5μm) adaptive optics (AO) wavefront (WF) sensing using natural guide stars. With larger formats and improved readout integrated circuits (ROICs), this technology shows great promise for more sophisticated wavefront correction and also, potentially, lower background astronomy applications. This opens the path to larger format arrays optimized for either AO WF sensing or low background applications. We present Selex-UH initiatives in both areas.
