CASSEGRAIN INSTRUMENTS
CASSEGRAIN INSTRUMENTS


This section contains information on UKIRT's suite of common user instruments for Cassegrain focus. These are not available for community use at this time. For information on the prime-focus Wide-Field Camera (WFCAM) go here .

UIST: 1-5um imaging and long-slit grism spectroscopy with R~1500-3500. Also integral-field spectroscopy and imaging- and spectro-polarimetry.
UFTI: 1-2.5um camera with 1024x1024 pixels; pixel scale 0.09". Imaging polarimetry and K-band 400 km/s FP also available.
CGS4: 1-5um long-slit grating spectrometer with R ~ 400-40,000.
IRPOL: UKIRT's polarimetry module for use with all instruments except Michelle, which has its own waveplates.
Michelle: 10-20um imaging and long-slit grating spectroscopy. Echelle spectroscopy and imaging/spectro-polarimetry also available. Instrument currently at Gemini
Visiting Instruments: Links to TRISPEC and other visitor instruments. No visitor instruments are scheduled for the forthcoming semester.

The graph below shows a plot of wavelength range against spectral resolution for the UKIRT cassegrain instruments. Imagers are plotted in blue, spectrometers in red. WFCAM covers essentially the same area as UFTI.
