Quantum Coating Featured In BBC Documentary

Quantum Coating was recently featured in BBC’s documentary, In Orbit: How Satellites Rule Our World.  Hosted by Maggie Aderin Pocock, the documentary reveals the vital role that satellites play in the modern world and explores the huge advances that have been made possible by satellites. 

Quantum was featured for its work coating twenty-one of the most sophisticated and nearly irreplaceable optical elements of the James Webb Space Telescope.  To complete this project, Quantum Coating technicians applied a proprietary gold film, 200 times thinner than a human hair, to the mirrors that will be part of the telescope.  The gold coating allows instruments aboard the telescope to detect the most distant objects in the universe by reflecting infrared light that has traveled through space and time.

Quantum Coating Completes Gold Mirror Coatings for James Webb Space Telescope (JWST) with 100% Success

Quantum Coating, Inc is pleased to announce a milestone in both optical coating and space exploration: The successful gold mirror coating on all flight optics for the Webb Telescope program. Over the past 15 months twenty-one of the most sophisticated and near irreplaceable optical elements were treated with Quantum's unique gold deposition process. All coatings were completed on schedule, meeting every requirement on every mirror.

Finishing all mirror coatings on schedule is another major success story for the Webb telescope mirrors" (Lee Feinberg, NASA).

It represents not just the coating event, but the completion of a huge engineering project" (John Mather, senior project scientist, JWST).

The principal assembly is the 6.5m Primary Mirror, which is an array of 18 hexagons, each 1.5m across and made from light weighted beryllium (Be). The telescope also has Secondary, Tertiary and Fine Steering mirrors. Transforming these mirrors from metal blanks took multiple trips across the US as they were machined, ground, polished and tested. The mirrors then traveled to Moorestown, NJ for the final, critical application of Quantum's proprietary reflective gold coating: a 120nm thick film that boosts the infrared reflectance to 99%.

Quantum Team

The JWST demanded near-perfect precision in every aspect of the project, from handling the large, almost irreplaceable Be substrates, to achieving near-perfect thickness uniformity over 1.5m curved surfaces. Quantum delivered on each requirement while managing film reflectance, stress and durability with the ability to survive cryogenic cycling to near absolute zero.

We are very proud," said Quantum President Dan Patriarca, "not just of our successful coating effort, but that we were able to play a very significant role in a scientific program of this magnitude. The technical challenges of this program, uniformity of less then 10nm over a 1.5M curved surface, high reflectivity from 0.8 to 26 microns and survivability in the extreme environment of outer space to name a few, presented a daunting task for our team. The successful completion of this program without error or exception has affirmed our competency and ability to meet such demands. It also expands our experience to take on similarly challenging programs in the future. We look forward to moving beyond this program and establishing ourselves as a premier coating house to the scientific community.

Quantum's involvement began in 2001, when the first gold coated Be samples were produced and dropped in liquid nitrogen, demonstrating their ability to withstand cryogenic temperatures. At that time, the program was known as Next Generation Space Telescope (NGST), replacing the venerable Hubble Telescope. In 2007 Quantum was awarded the contract for gold coatings on the telescope, by then known as James Webb Space Telescope (JWST), named for the NASA administrator.

Over the next two years, Quantum expanded to meet its new needs, investing in a new 1800ft2 Class 1000 cleanroom facility, a custom designed 96" coating chamber and a metrology laboratory with a variety of specialized instruments for testing reflectance, thickness, stress, roughness and cryo-cycling.

Four years later the investment has proved to be well worth it: the final primary segment was coated last month, bringing to a spectacularly successful end Quantum's 10 year involvement in the Webb Telescope program.


James Webb Space Telescope Overview:

The James Webb Space Telescope (sometimes called JWST) is a large, infrared-optimized space telescope. The project is working to a 2018 launch date. Webb will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. Read more...

Observatory: The Optical Telescope Element (OTE)

The Optical Telescope Element (OTE) is the eye of the James Webb Space Telescope Observatory. The OTE gathers the light coming from space and provides it to the science instruments. Webb needs a large mirror to collect as much light as possible to see galaxies from the beginning of the Universe. Read more about the JWST Optical Telescope Element

June, 2010

On June 24th, 2010 the first full size (1.5m) hexagonal beryllium primary mirror segment was coated with protected gold at Quantum Coating Incorporated. This represents the culmination of a two-year effort and is the final major milestone in our program to develop and qualify the gold coatings to be used on the James Webb Space Telescope (JWST). The preliminary segment, known as the Engineering Development Unit (EDU) will not become part of the telescope’s primary array, which consists of 18 almost identical hexagons, but will be used for ground based testing and will serve as a spare.

The EDU will be used for evaluation: before proceeding with the primary segments it is critical to verify that the combination of our high-reflectance gold coating with light-weighted Beryllium mirror technology performs as predicted in all respects. Several important performance elements – such as cryogenic cycling, durability, stress and reflectance - had already been demonstrated in the course of prior qualifying stages and the successful coating of the Tertiary Mirror in April of this year.  The full-size EDU brought additional critical requirements into play: control of thickness uniformity over the 1.5m off-axis parabolic surface, and control of the coated aperture to within a fraction of a millimeter along the curved edges of the hexagon. Both aspects were successfully demonstrated through the innovative design and meticulous attention to detail that has become hallmarks of Quantum’s Aerospace Division.

The Webb telescope will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

Several innovative technologies have been developed for JWST. These include a folding, segmented primary mirror, adjusted to shape after launch; ultra-lightweight beryllium optics; detectors able to record extremely weak signals, microshutters that enable programmable object selection for the spectrograph; and a cryocooler for cooling the mid-IR detectors to 7K.

Looking forward, the next flight optic, the Fine Steering Mirror (FSM) will be coated in July, followed by the first of the Primary Mirror Segments in September 2010. Launch is scheduled for 2014. For more about JWST, visit: http://www.jwst.nasa.gov/about.html

In May 2009 the JWST chamber was used to coat two 1.5m zerodur telescope mirrors with our FSS99-106 protected silver. The coatings were uniform to within 2% across the full clear aperture and met all durability and reflectance requirements.

This not only demonstrated the operational readiness of the machine, but also served as an extreme load test of the substrate rotation assembly: the combined weight of each glass optic in its fixture approached 2,500lbs, more than 6 times the projected weight of a JWST Primary Segment when fully fixtured.

Coatings on JWST telescope optics will start later this year.

Denton Coatings has successfully completed the anti-reflection (AR) coatings on the Schmidt Corrector for the 0.95m high field of view photometer on the Kepler Mission. The corrector required specially designed broad band AR coatings that were resistant to radiation damage and had low reflectance over the wavelength range 400nm to 900nm and. The Kepler Mission, a NASA Discovery mission, is specifically designed to survey our region of the Milky Way galaxy to detect and characterize hundreds of Earth-size and smaller planets in or near the habitable zone. The habitable zone encompasses the distances from a star where liquid water can exist on a planet's surface. Results from this mission will allow us to place our solar system within the continuum of planetary systems in the Galaxy. Launch is scheduled for February 2009. For more about Kepler, visit:
