GriF is a new observing mode of KIR, the infrared camera of the PUEO CFH adaptive optics system. It is an integral field spectrograph working in K-band and made of an ambiant-temperature Fabry-Perot and a cooled grism, placed inside the cryostat. With a spectral resolution of 2000, the former selects narrow-band images that are spatially separated by the latter. Focal masks in the cryostat prevent from the overlapping these images. Thus, GriF combines the high angular resolution with the spectroscopic diagnosis. After the etalon installation last december, we obtain our first GriF images in the OMC-1 region, in the H2 v=1-0 S(1) band. Results from these observations will be presented during this meeting.
