1. Ultra Violet Imaging Telescope (UVIT):

To image the sky simultaneously in  three wavelengths, one covering the far UV band (130 – 180 nm) and the second sensitive in near UV (200 – 300nm) and Visible (320 – 550 nm) bands.  The detector in each channel is a photon counting device. Multiple choices of filters are available in each channel.

2.Soft X-ray Telescope (SXT):

Is a focusing X-ray telescope with an X-ray CCD imaging camera. This will work primarily in photon counting mode, recording the position, time and energy of every detected photon in the energy range 0.3-8 keV.

3. Large Area X-ray Proportional Counters (LAXPC):

Comprising three identical proportional counters of effective area > 8000 cm2 @ 5-30 keV.  This payload is non-imaging. Its main purpose is to record variation of total intensity of sources within its 1-degree field of view, with high time resolution and moderate spectral resolution over a large spectral band from 3 to 80 keV.

4. Cadmium-Zinc-Telluride Imager (CZTI):

Is a hard X-ray coded mask camera working in the band 10-100 keV. It has better spectral resolution than the LAXPC and a coarse imaging capability by the coded mask..

5. Scanning Sky Monitor (SSM):

Æ For detection of new X-ray transients and monitoring of known X-ray sources in 2.5 – 10 keV region..

In addition, there is a Charged Particle Monitor (CPM) to detect high-energy particles during the satellite orbital path and alert the instrumentation.
