摘要
MTRI is the mid infrared instrument planned for the NGST. Working in the 5 mum - 28 mum 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: in imaging mode, with a, Field Of View of 1.3 arcmin x 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 mum and 1.0 mum, with a spectral resolution R = lambda/Deltalambda around 100.
