Optical and infrared astronomy is one of the major fields for exploring the Universe. ATC has been playing an important role in developing astronomical instruments for the Subaru Telescope, located at the summit of Maunakea in Hawaii, as well as for the Thirty Meter Telescope (TMT), which is a state-of-the-art telescope that is under construction.<\/p>\n\n\n\n

The InfraRed Imaging Spectrograph (IRIS) is one of the first light instruments for the Thirty Meter Telescope. IRIS is being developed through international collaboration between the United States, Canada, China, and Japan. ATC, representing the Japanese contributions to the instrument, is responsible for delivering an infrared camera for IRIS. We are addressing unprecedented technical challenges unique to IRIS, including diffraction-limited optics working at liquid-nitrogen temperatures (~ -200 degC), cryogenic driving mechanisms that need to be maintenance-free for 10 years, and precision astrometry at the 10 micro-arcsec level (in other words, measuring the position of stars on the sky to within 1\/100 millionth of 1 deg).<\/p>\n\n\n\n
