NINJA (Near-INfrared and optical Joint spectrograph with Adaptive optics) is an Optical-to-NIR spectrograph optimized for the Laser Tomographic Adaptive Optics (LTAO)* system at the Subaru telescope, realized by the Adaptive Secondary Mirror. It consists of at least two spectrograph units, one is in the optical(0.4-0.9um) and the other in the NIR(0.9-2.5micron). The development of the NIR spectrograph is supported by JSPS KAKENHI Grant 21H04997. Part of the development is supported by the Advanced Technology Center, National astronomical observatory of Japan.
