  • ELT MICADO

    MICADO logo

    MICADO is the first light imager for the ESO Extremely Large Telescope (link to ESO webpage www.eso.org) currently build on Cerro Armazones in Chile. It will provide the ELT the capability for diffraction limited imaging at near-infrared wavelengths. more

  • Wendelstein WWFI

    WWFI

    One Nasmyth port of the 2m robotic telescope at the Wendelstein Obseratory has been equipped with a wide-field corrector which preserves the excellent image quality (< 0.8” median seeing) of the site (Hopp et al. 2008) over a field of view of 0.7 degrees diameter. The available field is imaged by an optical imager (WWFI, the Wendelstein Wide Field Imager) built around a customized 2 × 2 mosaic of 4k × 4k 15 μm e2v CCDs from Spectral Instruments. more

  • Wendelstein 3KK

    3KK

    One Nasmyth port of the 2m robotic telescope at the Wendelstein Observatory serves three different instruments which can be simultaneous in stand-by mode for a wide field of scientific application.
    The three channel optical-near-infrared imager 3kk is already in regular use science January 2016. The high resolution spectrograph FOCES receives photons by a selecting mirror and a fiber connection to its lab. The field spectrograph VIRUSW will be eventually installed using a further pick-off dichroite, but is right now on loan to the McDonald Observatory 2.7m H.Smith tetescope. All three instruments have been developed and build by the instrument developers team of our group.
    3kk is built around two customized 2k * 2k 15 um Fairchild CCDs camera from Apogee (one for the blue bands, one for the red ones) and a near infrared 2k * 2k 18 um HAWAII2HRG detector. The NIR camera was developed together with the Institute for Astronomy of the University of Hawaii (www.ifa.hawaii.edu). more

  • VIRUS-W

    virus-front

    VIRUS-W, built by the University Observatory in Munich and the Max-Planck Institute for Extraterrestrial Physics, is currently operated at the 2.7 m Harlan J. Smith Telescope of the McDonald Observatory in Texas. One of the predominant features of VIRUS-W is that it implements a so-called Integral Field Unit (IFU). Other than the usual slit at the entrance aperture of a spectrograph, an IFU delivers spectra in a two-dimensional field of view, a spectrum for every pixel in the image so to speak. more
