A novel compact 4-channel beam splitter based on a Kösters-type prism
Jochen Greiner, Uwe Laux
We introduce a novel compact 4-channel beam splitter which is based on a combination of dichroic coatings and internal total reflection, similar in concept to the interference doub…
TAUKAM: a new prime-focus camera for the Tautenburg Schmidt Telescope
Bringfried Stecklum, Jochen Eislöffel, Sylvio Klose +6
TAUKAM stands for "TAUtenburg KAMera", which will become the new prime-focus imager for the Tautenburg Schmidt telescope. It employs an e2v 6kx6k CCD and is under manufacture by Sp…
GRIPS - Gamma-Ray Imaging, Polarimetry and Spectroscopy
J. Greiner, K. Mannheim, F. Aharonian +65
We propose to perform a continuously scanning all-sky survey from 200 keV to 80 MeV achieving a sensitivity which is better by a factor of 40 or more compared to the previous missi…
HERMES: a high-resolution fibre-fed spectrograph for the Mercator telescope
Gert Raskin, Hans Van Winckel, Herman Hensberge +18
The HERMES high-resolution spectrograph project aims at exploiting the specific potential of small but flexible telescopes in observational astrophysics. The optimised optical desi…
GROND - a 7-channel imager
J. Greiner, W. Bornemann, C. Clemens +19
We describe the construction of GROND, a 7-channel imager, primarily designed for rapid observations of gamma-ray burst afterglows. It allows simultaneous imaging in the Sloan g'r'…
URAT: astrometric requirements and design history
N. Zacharias, U. Laux, A. Rakich +1
The U.S. Naval Observatory Robotic Astrometric Telescope (URAT) project aims at a highly accurate (5 mas), ground-based, all-sky survey. Requirements are presented for the optics a…
