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.
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.
There are varieties of telescope instrument types, usually classified by the segment of the electromagnetic spectrum they detect. Fortunately, for us, the earth’s atmosphere makes it difficult for some portions of the spectrum to reach earth, such as x-rays and infrared light. In order to detect radiation in space, x-ray telescopes are launched above the earth’s atmosphere. For ground-based optical telescopes, visible light does pass through the atmosphere, allowing them to make observations of visible light from space right on earth.
All of these highly sophisticated telescopes systems use cutting edge sensor technology, allowing scientists to image a wide range of faint and/or fleeting astronomical phenomena in ultra-high resolution. Hamamatsu aims to enable the advancement of astronomy by way of our sensor and calibration technologies.
Negating the effects of atmospheric turbulence using high resolution and high speed.
Efficient and precise calibration of cameras and spectrographs using high brightness and broadband output light sources.
Imaging the fast dynamics of the sun with high dynamic range and high resolution.
Detecting the faint and fast dance of light in the sky with high sensitivity and high resolution.
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.
Understand the challenges astronomers have faced with their applications, and how our camera technology has been used to overcome these challenges. Read valuable interviews with astronomers whose studies enable them to discover and explore unknown celestial bodies, astronomical phenomena and more.
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.
