摘要

SNIFS is an integral field spectrograph devoted to the observation of supemovae. This instrument is today in the manufacturing phase and should be able to observe supemovae at the end of this year (2003) on the 2.2m telescope of University Hawaii. The concept of SNIFS is to split the 6" x 6" field of view into 225 samples of 0.4" x 0.4" through a microlens array. Then the spectral decomposition of each sample is imaged on a 2k x 4k CCD. In order to cover all the large spectral range with a high resolution, the spectrograph is composed of two modules, one for the blue wavelengths (320 nm to 560nm) with a resolution around 1000 at 430 nm and one for the red wavelengths (520 nm to 1 μm) with a resolution around 1300 at 760 nm. First we will present the optical design and detail the function of each optical component. Then the mechanical design will be shown with some maps of the structure. Finally the first pictures taken during the alignments will be displayed.
