GROND - Gamma-Ray Burst Optical/Near-Infrared Detector

GROND is an imaging instrument to investigate Gamma-Ray Burst Afterglows and other transients simultaneously in seven filter bands. Several dichroic beamsplitters feed light into three NIR channels and four visual channels, each equipped with its own detector. GROND has become operational in 2007.

GROND has been built by the high-energy group of MPE in collaboration with the LSW Tautenburg and ESO. GROND is operated as a PI-instrument at the MPI/ESO 2.2m telescope on La Silla (Chile).
