Instrumentation at the Subaru Selescope

Abstract

We present the current status and future plan of the instruments at the Subaru Telescope. The Hyper Suprime- Cam, which is a wide-field optical imager at the prime-focus and started the science operation in 2014, has been extensively used for a large survey program and general open use observations. The Prime Focus Spectrograph started the commissioning of the first subsystem, the Metrology Camera System, in 2018 and has been continuing the installation of the other subsystems. As the third system of the wide-field instrumentation suite, ULTIMATE-Subaru has started preliminary design for the GLAO system and conceptual designs for the science instruments. We will also present the status, upgrades, and future plan of the other facility instruments and visiting instruments.
