Abstract

We present the design of the DDRAGO wide-field multi-channel imager for the 1.3 meter COLIBRÍ telescope for the Observatorio Astronómico Nacional in Mexico. The instrument has blue and red channels which have fields of 26 arcmin. It also delivers a faster infrared beam to the CAGIRE imager which has a field of 22 arcmin. The instrument is designed to provide initial follow-up of GRBs detected by the ECLAIRs instrument on the SVOM satellite. 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
