Abstract : The Spectroscopic Investigation of Nebular Gas (SING) payload is a near ultraviolet (NUV) imaging spectrograph, which is designed to operate in the wavelength range from 1400 Å to 2700 Å, with a spectral resolution of ~2 Å at 2200 Å. The Observational Targets for SING are supernova remnants, planetary nebulae, star formation in nearby galaxies along with emission from their extended halos. In this poster, we will present opto-mechanical alignment and ground calibration plans of SING spectrograph. In addition, we will also discuss about the possibility of contamination during the alignment, calibration, storage and transportation operations, which could affect the optical performance of the telescope.
