Canon USA continues to dabble in area tasks together with Canon Inc.  Canon USA is sending Mission Dragonfly 120 Canon RF 400mm f/2.8L IS II USM lenses. Mission Dragonfly is a global analysis workforce consisting of Yale College and the College of Toronto researchers.

About Mission Dragonfly

The Dragonfly Telephoto Array is a novel telescope idea designed to picture massive and very faint buildings within the evening sky. These buildings maintain vital clues to the distribution and nature of darkish matter, the elusive substance whose contribution to the entire mass-energy density of the Universe is 5 occasions increased than that of regular matter. These construction are arduous to see with typical telescopes resulting from a mix of scattered mild from vivid stars and their mosaicked detectors. Dragonfly harnesses the facility of commercially-available high-end telephoto lenses to deal with these points. The newest technology of Canon 400 mm f/2,8 lenses have excellent anti-reflection properties, owing to one of many first functions of nano-fabricated coatings with sub-wavelength buildings on optical glasses.

Press Launch

MELVILLE, NY, November 18, 2021 – Canon U.S.A. Inc., a frontrunner in digital imaging options, as we speak introduced the corporate will present technical help to Mission Dragonfly, a global analysis workforce from Yale College, and the College of Toronto, in its plan to increase the Dragonfly Telephoto Array. The corporate will present the mission with 120 Canon EF 400mm f/2.8L IS II USM large-aperture super-telephoto single-focal size lenses, and its guardian firm, Canon Inc., will present technical help.

The Dragonfly Telephoto Array is a telescope array outfitted with a number of Canon large-aperture super-telephoto single focal size lenses – particularly, the Canon EF 400mm f/2.8L IS II USM lens. The telescope was designed in 2013 by Mission Dragonfly, a global analysis workforce from Yale College and the College of Toronto. The Dragonfly Telephoto Array is able to capturing photographs of galaxies which are so faint and enormous that they’d escaped detection by even the biggest typical telescopes. Its mission is to check the low floor brightness universe to elucidate the character of darkish matter and to make the most of the idea of distributed telescopes.

In assist of this analysis, Canon supplied technical help by supplying 40 Canon EF 400mm f/2.8L IS II USM lenses in 2015, increasing the array to 48 lenses with 24 telescopes bundled on two separate mounts. Since then, the analysis workforce has produced vital leads to extragalactic astronomy, together with discovering the ultra-diffuse galaxy Dragonfly 44 in 2016 and the identification of a galaxy that lacks darkish matter, NGC 1052-DF2, in 2018.

This time, Canon will present technical help by supplying 120 Canon EF 400mm f/2.8L IS II USM lenses to the analysis workforce, additional increasing the telescope array. With a complete of 168 lenses, the telescope array has a light-gathering functionality equal to that of a refracting telescope of 1.8 meters in diameter, with a focal size of solely 40 cm, and is predicted to open new home windows on the universe.

Canon is dedicated to contributing to the event of science and expertise by leveraging the technological strengths it has cultivated as a number one imaging firm.

Message from Professor Pieter van Dokkum of Yale College feedback

The Dragonfly Telephoto Array is the pre-eminent survey telescope for locating faint, diffuse objects within the evening sky. It has enabled us to find ultra-diffuse galaxies and different low-surface brightness phenomena—rendering photographs that deepen our understanding of how galaxies are shaped and offering key insights into the character of darkish matter. The preliminary array was outfitted with 48 Canon EF 400mm telephoto lenses that includes anti-reflection coatings that mitigate the consequences of sunshine scattering, overcoming the constraints of typical telescopes in detecting faint buildings. The lenses are coupled to monolithic wide-field detectors that let wonderful error management. With the addition of 120 of those lenses, in a newly developed configuration permitting extraordinarily slender filters for use, Dragonfly would be the strongest wide-field spectroscopic line mapping machine in existence. A significant aim of the subsequent iteration of the Dragonfly array is to detect and research the faint gasoline thought to exist round and between galaxies. By opening this new window on the cosmos, Dragonfly will deal with a number of the most crucial questions in astrophysics as we speak.
