摘要:

我们提出了一个概述的设计IRIS,红外(0.84 - 2.4微米)积分场摄谱仪和成像相机的三十米望远镜(TMT)。IRIS具有极低的波前误差(<30 nm)和机载波前传感器,将利用窄场红外自适应光学系统(NFIRAOS)的高角分辨率,在30米孔径的衍射极限处解剖天空。该仪器的主要光谱分辨率为4000,空间采样从4毫角秒开始,将具有无与伦比的能力来探索高红移星系、银河系中心、恒星形成区和几乎任何天体。本文总结了整个设计方案和基本功能。在设计创新中,包括小透镜和切片器积分场单元的组合、新的4Kx 4k探测器、极其精确的大气色散校正、红外波前传感器和非常大的真空低温系统。

英文摘要:

We present an overview of the design of IRIS, an infrared (0.84 - 2.4 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.
