Abstract : The high resolution optical/UV images have so far been provided by the Hubble Space telescope (HST) since 1990s. The high spatial resolution imaging of the HST is limited to very small fields. As the mission is approaching the end of its life time, it is unlikely to be available for a very long period. As the 2030s will produce deep sky images in the optical and IR regions, a similar coverage in the Ultraviolet are not addressed by any planned mission. This is where India with its capacity to launch and operate space observatories, can fill the gap. The UVIT was a capability demonstration and it is important to take this strength to create the next generation UV-¬optical observatory class space telescope in the next decade, to fill the gap in the international scene. In order to fill the gap in the UV space astronomy, Indian astronomical community has submitted a proposal, Indian Spectroscopy and Imaging Space Telescope (INSIST), to ISRO. INSIST is an observatory class mission aims to do imaging with high spatial resolution (0.2") covers 0.25square degree FOV with the sensitivity of 28th magnitude in the UV for an exposure of 1ksec and a multi object spectroscopy feasibility with a spectral resolution of R~2000 in UV. During the design phase, various optical configurations have been considered and the merits and demerits of each design has been studied. In this talk we are going to discuss the details of the design considered for INSIST
