Abstract : The back-end instruments are backbone of any Astronomical Telescope. We are going to have a 2.5-m telescope at the Mt.Abu Infrared Observatory (MIRO) very soon. There is, therefore, requirement of a set of instruments to extract science from this telescope.In this regard, a Near-Infrared imaging spectro-polarimeter is being designed and developed at the Astronomy & Astrophysics Division of the Physical Research Laboratory, Ahmedabad. The instrument will facilitate different techniques i.e Imaging, Spectroscopy & Polarimetry for the observation. It will operate in the near-IR wavelength range of 0.8 micron – 2.5 micron (Y, J, H, Ks bands). The polarization function will be used in combination with the imaging or spectroscopic mode, in addition to the imaging and spectroscopy operations available. The design will enable rapid switching between the various modes of observations. With all these multi-purpose functions the instrument is expected to serve as a workhorse instrument on the 2.5-m telescope. A large range of science topics (covering solar system to extragalactic astronomy) are proposed to be studied using this instrument. This contribution will cover the basic design goals for the instrument. The necessary technical details and the current status of the design will also be discussed at the conference.
