WIRC+Pol: a low-resolution near-infrared spectropolarimeter
Samaporn Tinyanont, Maxwell A. Millar-Blanchaer, Ricky Nilsson +14
WIRC+Pol is a newly commissioned low-resolution (R~100), near-infrared (J and H band) spectropolarimetry mode of the Wide-field InfraRed Camera (WIRC) on the 200-inch Hale Telescop…
The Infrared Imaging Spectrograph (IRIS) for TMT: advancing the data reduction system
Gregory L. Walth, Shelley A. Wright, Nils-Erik Rundquist +19
Infrared Imaging Spectrograph (IRIS) is the first light instrument for the Thirty Meter Telescope (TMT) that consists of a near-infrared (0.84 to 2.4 micron) imager and integral fi…
Intra-pixel response characterization of a HgCdTe near infrared detector with a pronounced crosshatch pattern
Charles Shapiro, Eric Huff, Roger Smith
The "crosshatch" pattern is a recurring "feature" of HgCdTe arrays, specifically the Teledyne HAWAII family of near infrared detectors. It is a fixed pattern of high frequency QE v…
Precision Projector Laboratory: Detector Characterization with an Astronomical Emulation Testbed
Charles Shapiro, Roger Smith, Eric Huff +7
As astronomical observations from space benefit from improved sensitivity, the effectiveness of scientific programs is becoming limited by systematics that often originate in poorl…
