Abstract

PFS (Prime Focus Spectrograph) is an ultra-wide-field, multi-object spectrograph currently being commissioned at Subaru telescope. The focal plane is made of ∼2400 science fibers and fiber positioners at the telescope prime focus, covering a field of view of 1.3 deg in diameter. The science fibers will be connected to 4 identical spectrograph modules, each receiving ∼600 fibers. Every spectrograph module will host 3 cameras, covering the blue (380–650 nm), red (630–970 nm) and near-infrared (940–1260 nm) wavelengths. This presentation will focus on the completion of the PFS spectrograph modules at the Subaru telescope. We will present their integration and test processes and measured performance, as well as the technical challenges encountered along the way, and the solutions used to correct them.
