摘要:

IRIS是一种近红外(0.84至2.4微米)积分场摄谱仪和宽视场成像仪,正在开发用于30米(TMT)的第一束光。它安装在先进光学(AO)系统NFIRAOS上,并集成了仪器上的波前传感器(OIWFS),以实现波长超过1微米时的衍射极限空间分辨率。IRIS具有中等的光谱分辨率(R ~ 4,000 - 8,000)和连续视场的大带通,将在天体物理科学的几乎每个领域开辟新的机会。它将能够解析泰坦数十公里的表面特征,同时也能以单个恒星形成区域的规模绘制遥远的星系。本文总结了整个设计和能力,并包括从接近完成的初步设计阶段的结果。

英文摘要:

IRIS is a near-infrared (0.84 to 2.4 microns) integral field spectrograph and wide-field imager being developed for first light with the Thirty Meter (TMT). It mounts to the advanced optics (AO) system NFIRAOS and has integrated on-instrument wavefront sensors (OIWFS) to achieve diffraction-limited spatial resolution at wavelengths longer than 1 micron. With moderate spectral resolution (R ~4,000 - 8,000) and large bandpass over a continuous field of view, IRIS will open new opportunities in virtually every area of astrophysical science. It will be able to resolve surface features tens of kilometers across Titan, while also mapping the distant galaxies at the scale of an individual star forming region. This paper summarizes the entire design and capabilities, and includes the results from the nearly completed preliminary design phase.
