本文概述了30米望远镜(TMT)红外(0.85-2.5微米)整体场光谱仪和成像相机IRIS的设计。具有极低的波前误差(<lt；30 nm)和机载波前传感器，IRIS将利用窄场红外自适应光学系统(NFIRAOS)的高角度分辨率在30米口径的衍射极限下剖析天空。该仪器的主要光谱分辨率为4000，空间采样开始于4毫角秒，将创造出无与伦比的能力来探索高红移星系、银河中心、恒星形成区域和几乎任何天体物理对象。本文总结了整个设计和基本功能。其中的设计创新包括组合了微透镜和切片器集成场单元、新的4Kx4k探测器、极其精确的大气色散校正、红外线波前传感器和超大型真空低温系统。
We present an overview of the design of IRIS, an infrared (0.85 - 2.5 micron) integral field spectrograph and imaging camera for the Thirty Meter Telescope (TMT). With extremely low wavefront error (<30 nm) and on-board wavefront sensors, IRIS will take advantage of the high angular resolution of the narrow field infrared adaptive optics system (NFIRAOS) to dissect the sky at the diffraction limit of the 30-meter aperture. With a primary spectral resolution of 4000 and spatial sampling starting at 4 milliarcseconds, the instrument will create an unparalleled ability to explore high redshift galaxies, the Galactic center, star forming regions and virtually any astrophysical object. This paper summarizes the entire design and basic capabilities. Among the design innovations is the combination of lenslet and slicer integral field units, new 4Kx4k detectors, extremely precise atmospheric dispersion correction, infrared wavefront sensors, and a very large vacuum cryogenic system.
