Resumen:
We present the design of the DDRAGO wide-field multi-channel imager for
the 1.3-meter COLIBRI telescope for the Observatorio Astronomico
Nacional in Mexico. The instrument is designed to provide initial
follow-up of GRBs detected by the ECLAIRs instrument on the SVOM
satellite.
DDRAGO has blue (gri) and red (zy) channels which use 4k by 4k CCDs and
give fields of 26 arcmin. It also delivers a faster infrared (JH) beam
to the CAGIRE imager which uses a 2k by 2k detector and gives a field of
22 arcmin.
DDRAGO is a descendent of the successful RATIR imager, but the optical
design is significantly more complex to allow much wider fields. We
summarize the optical, optomechanical, structural, and control design.
