Descripción
IO:I is the near-infrared imaging component of the IO suite of instruments. It uses a 2048x2048 pixel Hawaii 2RG 1.7μm cutoff detector with a field of view of 6.3 arcminutes, a pixel scale of 0.18 arcsec, and currently a single H-band (1.5-1.8 micron) filter. It became available as a common-user instrument in August 2015.
