Paper Abstract

The Prime Focus Spectrograph (PFS) is a new multi-fiber spectrograph on Subaru telescope. PFS will cover around 1.4 degree diameter field with ~2400 fibers. To ensure precise positioning of the fibers, a metrology camera is designed to provide the fiber position information within 5 μm error. The final positioning accuracy of PFS is targeted to be less than 10 μm. The metrology camera will locate at the Cassegrain focus of Subaru telescope to cover the whole focal plan. The PFS metrology camera will also serve for the existing multi-fiber infrared spectrograph FMOS.
