Astronomy is a natural science that involves the observation of the extraterrestrial. This field studies near-Earth objects and other astronomical phenomena to help find the answers to the origin of the universe, to understand our solar system and galaxy, and to discover the laws of matter. In astronomy, various imaging technologies are used, such as solar imaging and spectroscopy, to study the sun's activity and Earth's upper atmosphere where auroras occur, for example. Imaging technologies based on image sensors and cameras are utilized at telescopes around the world.

Astronomical observation with extremely large telescopes

Large telescopes are used to observe exoplanets and protoplanetary systems, to search for signs of life, and to study the nature of dark energy by directly measuring the universe's expansion.

Large telescopes such as the Subaru Telescope, the Thirty Meter Telescope (TMT), the Keck Telescope, and the Gemini Telescope on the summit of Mauna Kea on the island of Hawaii, the Alma Telescope in the Atacama Desert in Chile, and the Canary Large Telescope on the island of La Palma in the Canary Islands have been installed in many parts of the world and continue to be used for observations.

Our efforts for astronomy

Hamamatsu Photonics has been providing various products for the field of astronomy, such as image sensors for large telescopes and infrared detectors for astronomical satellites. Below are examples of our collaborations with the astronomical community.

Usage examples: CCD image sensors for the Prime Focus Camera of the Subaru Telescope

The Subaru Telescope is an extremely large telescope on the summit of Mauna Kea, Hawaii. One of the world's most powerful telescopes, it is used to measure the history of cosmic expansion and dark energy, and it directly observes the distribution of dark matter.

Our CCD image sensor is used in the Prime Focus Camera for the Subaru Telescope. The CCD sensor has a unique, full-depletion structure and high sensitivity at long wavelengths, making it possible to observe at high resolution a wide range of faint objects that had been impossible to observe with conventional sensors.


HAMAMATSU's CCD image sensors are used in parts of the Subaru Telescope.
