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.
Instrument for ground-based telescope
GROND was build by MPE in collaboration with LSW Tautenburg and ESO and is operated at the 2.2m MPG/ESO telescope La Silla.
GROND is mounted at the MPI/ESO 2.2m telescope on La Silla (Chile), and is operational since 2007.
