The Ultra Violet Imaging Telescope on Astrosat, aims to provide flux calibrated images of the sky at a spatial resolution of ~ 1.5 second of arc in two ultraviolet channels, FUV (1200-1800 A) and NUV (1800-3000 A), simultaneously with ~ 0.5 degree field of view. In addition to the two ultraviolet channels, simultaneous imaging is also done in the VIS 3500-5500 A). The ultraviolet range of 1200 - 3000 A, and visible range of 3500 to 5500 A would be covered through the use of broad and narrow band filters.

Some of the most interesting scientific aims of the proposed ASTROSAT involve multi-band observations in wavelengths extending from the hard X-rays to the visible band, e.g. correlated temporal variations in visible, UV, soft and hard X-ray bands to investigate origin and machanism of the emission of radiations in active galactic nuclei. Therefore, apart from the observations which are primarily designed for ultraviolet objects, a primary objective of the project is to provide the UV and visible band component of the multi-band observations of galactic and extragalactic objects.
