TIMMI 2: a new MIR multimode instrument for ESO

We present here briefly the scientific objectives, the optical and mechanical design as well as the main components and observing modes of the new thermal IR multimode instrument for the 3.6-m telescope of European Southern Observatory at La Silla, Chile. Also we describe shortly the software package consisting of instrument control, data acquisition, quick look data reduction, calibration control and off-line data reduction that is necessary to operate the instrument and reduce the data. New values of refractive index of KRS-5 at low temperatures are given.
