Current Status and Future Plans for Infrared Detectors from Teledyne: ASIC, , HAWAII-4RG, and Photon Counters
Klaus W. Hodapp, Donald N. B. Hall

Abstract: We will review the current status of infrared detector arrays from Teledyne,, formerly Rockwell, and discuss our plans for future development of larger , detector arrays and of photon counting detectors for wavefront-sensing , applications., , HAWAII-2RG detector arrays have now been thoroughly tested for JWST and are in, operation, among others, in UH's ULBCAM and CFHT's WIRCAM. We have recently, demonstrated operation of the HAWAII-2RG detectors using the "Sidecar" ASIC, controller, which will greatly simplify readout electronics. Teledyne is ready, to build devices in 4Kx4K format, and is waiting for a launch customer. In, addition to the high-quality CdZnTe-substrate detector material, Teledyne has, promising results on SI-substrate HgCdTe detector material, with the prospect, for a significant reduction in detector cost., , Together with UH, Teledyne is exploring possible techologies for photo-, counting, very fast reading detector arrays. The first application would be, a relatively small detector array intended for use in wavefront-sensing , applications.
