Detector developments at ESO to prepare for the E-ELT era

Abstract

ESO has a very active on-going detector development program to not only meet the needs of the current crop of instruments for the VLT, but is also actively involved in gathering requirements and developing detectors for the challenging instruments being proposed and in design for the E-ELT. This paper provides an overall summary of the detector requirements of the various E-ELT instruments and the many interesting detector developments ESO is involved in to meet these needs. Most of these instruments and detector developments are described in more detail in other papers at this conference.

Development of HgCdTe large format MBE arrays and noise-free high speed MOVPE EAPD arrays for ground based NIR astronomy

“…As shown in Table 1, for the extremely large telescope (ELT) a large number of affordable 4kx4K near infrared detectors are needed in the wavelength range of 0.8-5um [1]. This wavelength range will be covered by HgCdTe arrays with cutoff wavelengths ranging between λ c =1.7μm to 5.3μm.…”
