Ultra Violet Imaging Telescope (UVIT) to image the sky simultaneously in three wavelengths, one covering the FUV band (130 – 180 nm) and the second sensitive in NUV (200 – 300nm) and Visible (320 – 550 nm) bands. Image resolution is ~ 1.8” in NUV compared to ~ 6” of GALEX. (NUV, FUV and Optical imaging; intensity variation).
Soft X-ray Telescope (SXT) using X-ray reflecting mirrors and X-ray CCD for imaging and spectral studies in 0.3 – 8.0 keV band (Soft X-ray energies; imaging in X-rays)
Three identical Large Area X-ray Proportional Counters (LAXPC) covering 3-80 keV region for variability studies of X-ray Binaries and other cosmic sources. It has atleast five times more effective area above 25 keV compared to the Rossi X-ray Timing Explorer (RXTE). (Primary goal – fast time variability and wide band spectral coverage)
Cadmium-Zinc-Telluride Imager (CZTI) array with coded mask aperture extends the high energy limit (10-100 keV band) for spectral studies. (extend high energy range, good spectral energy resolution if no source confusion; solid state detectors)
Scanning Sky Monitor (SSM) for detection of new X-ray transients and monitoring of known X-ray sources in 2.5 – 10 keV region.
