Abstract
MIRI is the mid infrared instrument planned for the NGST. Working in the $5~\mu {\rm m} -28~\mu {\rm m}$ band, it includes 3 units: a spectrograph, an imager and a calibration facility. We describe here briefly MIRIM, the MIRI imager channel as it is at the end of the phase A study. MIRIM provides 3 observing modes: an imaging mode, with a Field Of View of 1.3 arcmin $\times$ 1.7 arcmin and a Pixel Field Of View of 0.1 arcsec/pixel, a coronagraphic mode and a low resolution mode for point sources, between $5~\mu {\rm m}$ and $10~\mu {\rm m}$ , with a spectral resolution $R=\lambda/\Delta\lambda$ around 100.
