Abstract

We present here details of the manufacture of a deployable image slicing IFU for UIST (a new imager spectrometer for UKIRT). We also present the alignment methods developed and used to achieve optimal transmission and give results for laboratory testing of the IFU at cryogenic temperatures in its operational configuration in UIST. These tests covered transmission, scattered light, alignment of exit pupils and the spatial and spectral PSFs. The calibration and automatic data reduction methods which produce spectra (in the form of an x, y, λ data-cube) aligned in wavelength and the two spatial dimensions for all the observed pixels will be described.
