IRMOS

There's also concept of IRMOS (InfraRed Multi-Object Spectrometer). It is a multi-IFU near-IR spectrograph assisted by MOAO (Multi-Object Adaptive Optics). One of the concepts are shown here. In this concept the number of IFUs is 20, each IFU has 2" FoV, and the patrol field is 5 arcmin. diameter.
