In development is PFS (for Prime Focus Spectrograph), designed for galaxies Surveys for Cosmology research. It will collect Visible Light and Near Infrared, using 2400 optical fibers to simultaneously observe multiple targets. It has three arms, each covering a different Band, that image the same slit plane simultaneously.
The Hyper Suprime-Cam is an enhanced imaging camera with 870 million pixels and a 1.5° Field of View. It is coming into use in 2017.
