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.© (2003) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
