Abstract

We present an astronomical cooled grating spectrometer (LonGSp--Longslit Gornergrat Spectrometer) designed to work at Telescopio Infrarosso del Gornergrat. The covered spectral range is 0.9 divided by 2.5 micrometers and the resolving power is between 300 and 4000 depending on the order and slit width. The spectrometer employs a NICMOS 3 (256 X 256) engineering array of which a subsection of 70 X 40 is used.
