IOA Instrumentation GroupWelcomeThe Astronomical Instrumentation Group is currently building two fast-track NIR instruments which will provide much improved performance over instruments currently available. COHSI is a spectrograph for low dispersion spectroscopy of very faint (H~20) galaxies and offers simultaneous wavelength coverage of J and H in multi-object and integral field modes. CIRSI is a JH camera which has a mosaic of 4 10242 HgCdTe arrays for making deep NIR surveys. As part of our spectroscopy program we are also designing new spectrographs for 8-m telescopes which employ digital and hardware OH suppression. A prototype called CIRPASS will be built as an enhancement to COHSI. Other projects include the construction of a prototype integral field fibre feed called SPIRAL for the AAT which operates at optical wavelengths and a CCD system optimized for the UV. For more information about the instrumentation group contact one of the group, or email: Ian Parry irp@ast.cam.ac.uk or Craig Mackay cdm@ast.cam.ac.uk.
