| Summary:
The Multi-Channel Imager (MCI) is a powerful near-ultraviolet (NUV) and
visible imager onboard the Chinese Space Station Survey Telescope (CSST). The
MCI provides three imaging channels, which are the NUV channel, the
Optical-blue channel and the Optical-red channel, with the wavelength range of
255-430 nm, 430-700 nm, and 700-1000 nm, respectively. The three channels can
target the same field simultaneously. Each channel employs a CCD focal plane of
9216 x 9232 pixels and $sim$7.5 x 7.5 arcmin$^2$ field of view. The MCI’s
three channels feature unprecedented sensitivities and field of views, as well
as rich filter sets, which complements the NUV and visible capabilities of the
CSST for the high-precision photometry, the weak-signal detection, and the
related sciences. Here we present key design features, results of current
ground tests, and suggested observing strategies of the MCI.
