The effect of atmospheric turbulence is gentler at infrared wavelengths than in visible regime. Hence adaptive optics (AO) delivers better performance in the infrared regime. Robotic Adaptive Optics (Robo-AO) is an AO system for medium-sized telescopes jointly built by Caltech, USA and IUCAA, India. It works with minimal overheads and provides good sky coverage in both visible and infrared regime. The first version of Robo-AO does not have a high-quality NIR camera. For the second version called iRobo-AO, an NIR camera was developed at IUCAA to accommodate AO-corrected \(1.0^{\prime }\) field-of-view in near-infrared bands. It can be used as a science camera as well as a tip-tilt camera. Here we describe the salient features of the NIR camera like optics, optomechanical design, detector control system etc.

IUCAA 2 米望远镜上用于 iRobo-AO 的近红外相机

大气湍流的影响在红外波段比在可见光波段更温和。因此,自适应光学 (AO) 在红外区域提供更好的性能。Robotic Adaptive Optics(Robo-AO)是美国加州理工学院和印度IUCAA联合建造的中型望远镜AO系统。它以最小的开销工作,并在可见光和红外区域提供良好的天空覆盖。Robo-AO 的第一个版本没有高质量的 NIR 相机。对于名为 iRobo-AO 的第二个版本,IUCAA 开发了 NIR 相机,以适应近红外波段中 AO 校正的 \(1.0^{\prime }\) 视场。它可以用作科学相机以及倾斜相机。在这里,我们描述了 NIR 相机的显着特征,如光学、光机械设计、探测器控制系统等。
