SHARK-NIR的仪器将提供直接成像、日冕成像、双频成像和Y、J和H波段的低分辨率光谱，它将很快安装在大型双目望远镜上。SHARKNIR与SHARK-VIS（工作在V波段）和LBTI的LMIRCam（工作在K到M波段）结合使用，将利用三个不同波长的日冕同时观测。系外行星的搜索和表征，年轻的恒星系统，喷流和磁盘是主要的科学案例，但LBT AO系统的极端性能，尤其是在微弱的端区，将允许向科学开放难以实现其他类似的仪器，如AGN和QSO形态学研究。各种各样的日冕技术已经实现，如高斯Lyot，形瞳和四象限掩模，目的是可能有一个适合每个科学案例的日冕掩模，因为在对比度和内外工作角度方面的日冕要求取决于目标和要实现的科学。我们在这里报道SHARK-NIR的状态，它应该在2021年中期安装在LBT
SHARK-NIR in an instrument that will provide direct imaging, coronagraphic imaging, dual band imaging and low resolution spectroscopy in Y, J and H bands, and it will be soon installed at the Large Binocular Telescope. Used in combination with SHARK-VIS (operating in V band) and LMIRCam of LBTI (operating from K to M bands), SHARKNIR will exploit coronagraphic simultaneous observations in three different wavelengths. Exoplanets search and characterization, young stellar systems, jets and disks are the main science cases, but the extreme performance of the LBT AO systems, above all in the faint end regime, will allow to open to science difficult to be achieved from other similar instruments, such as AGN and QSO morphological studies. A variety of coronagraphic techniques have been implemented, as the Gaussian Lyot, Shaped Pupil and Four Quadrant masks, with the aim to possibly have a suitable coronagraphic masks for each science case, since the coronagraphic requirement in term of contrast and inner and outer working angle are depending on the target and on the science to be achieved. We report here about the SHARK-NIR status, that should be installed at LBT in mid-2021
