Description: MARTINI-III is an infra-red adaptive optics instrument designed to operate at Nasmyth focus in the Ground-based High Resolution Imaging Laboratory (GHRIL) at the William Herschel Telescope (WHT). The MARTINI-III system employs a polychromatic approach with wavefront distortions being sensed in the visible whilst the science target is recorded in the infra-red with the William Herschel Infra-red Camera (WHIRCAM). MARTINI-III makes use of a six-segmented mirror.
