To improve the instrument performance 2

      Comments Off on To improve the instrument performance 2

Before the engineering observation in March 2024, we PFS project carried out two major modification works at Subaru telescope. One of them is realignment of Metrology Camera System. “Metrology Camera System (MCS)” is the instrument installed on Cassegrain focus of Subaru telescope, and namely measures the fibers position on the prime focus plane. In fact, there was an accident during… Read more »

      Comments Off on 2nd On-Telescope Test of Metrology Camera System

Last year Metrology Camera System (MCS) was shipped to Subaru Telescope of National Astronomical Observatory of Japan, in Hawaii. After onsite integration and test, we installed MCS to the telescope and carried out optical alignment and on-telescope performance tests in June and October 2018. (See this for details)  MCS is installed to the Cassegrain focus at the bottom of the… Read more »

Since we published the article about the delivery of the Metrology Camera System (MCS) to Subaru Telescope in May this year, the member mainly from ASIAA (Academia Sinica Institute of Astronomy and Astrophysics, Taiwan) have visited Subaru Telescope a few times, in order to finalize the integration and proceed the on-site tests. In this article, we are going to talk… Read more »

Metrology Camera is at Subaru Telescope Now!

      Comments Off on Metrology Camera is at Subaru Telescope Now!

About one month has passed since Metrology Camera was shipped from Taiwan. Now it has arrived at Subaru Telescope at Maunakea in Hawaii. After shipping, from 23 April 2018, members from Academia Sinica, Institute of Astronomy and Astrophysics (ASIAA) visited to Hawaii Observatory of National Astronomical Observatory of Japan for final development. At Hilo base, ASIAA inspected Metrology Camera and… Read more »

Metrology Camera left Taiwan to Hawaii

      Comments Off on Metrology Camera left Taiwan to Hawaii

One of the PFS instrument “Metrology Camera” was finally shipped from Taiwan to Hawaii!! Metrology Camera  is an instrument used to measure the fibers position while we configure fibers to target objects. Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) in Taiwan has the responsibility for Metrology Camera development, and they tested its performances before shipping in the last a… Read more »

Updates on Development of Metrology Camera System

      Comments Off on Updates on Development of Metrology Camera System

“Metrology Camera System” is one of the PFS instrument subsystems under development by ASIAA (Academia Sinica Institute of Astronomy and Astrophysics, Taiwan). This is a small telescope system installed onto the Cassegrain Focus at the bottom of the Subaru telescope to look up the Prime focus, take the image of approximately 2400 back-illuminated fiber spots in one exposure with the large… Read more »

Metrology Camera System integration is progressing in Taiwan

      Comments Off on Metrology Camera System integration is progressing in Taiwan

Metrology Camera System to measure the positions of the fibers on the Subaru prime focus is being developed by ASIAA (Academia Sinica Institute of Astronomy and Astrophysics) , in Taiwan. After the success of the critical design review in 2015, the parts production and system integration are progressing, and all the mechanical parts have been manufactured. The photo below shows some of them…. Read more »
