The plate scale is 0.25"/pixel which provide a square FOV of 4.27 arcmin.
A set of 12 broad and narrow band filters will be available, plus a passband filter for spectroscopy. The filters were acquired via a consortium lead by  Dr. A. Tokunaga. Most filters were provided by Infrared Engineering, except the filters J, H and Ks which were provided by OCLI.
