- Description
- INdian Spectroscopic and Imaging Space Telescope (INSIST) is the next-generation UV-Optical space mission proposed by the Indian Astronomical community motivated by the great success of India's first multi-wavelength Astronomical satellite (ASTROSAT) where Ultra Violet Imaging Telescope (UVIT) was one of the main payload launched in 2015 by Indian Space Research Organisation. INSIST is primarily designed for photometry observation in three bands (g-[400nm-550nm], u-[300nm-400nm] and UV-[150nm-300nm]) simultaneously over 0.25 sq.degree field of view. INSIST is equipped with a low resolution [R?500] spectrograph for multi-Object slitless spectroscopy over the imaging field of view and also has a medium resolution [R?2000] spectrograph for multi-object slit spectroscopy in UV-band over ?6 sq.arcmin sky. MEMS-based Digital Micromirror Device [DMD] is used to form configurable slits for the selection of objects at the focal plane of the telescope for multi-object slit spectrograph. Multi-Object spectrograph with DMD as a re-configurable slit for INSIST is designed and the performance of the spectrograph is presented. 2023 World Scientific Publishing Company.
