VIAVI Innovations Propel NASA's Spectacular SPHEREx Mission
VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) has announced an exciting collaboration with NASA for the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) mission. This innovative mission, led by NASA's Jet Propulsion Laboratory (JPL) and the California Institute of Technology (Caltech), aims to revolutionize how we understand our universe.
Unraveling Cosmic Mysteries
SPHEREx is set to engage in an unprecedented all-sky infrared survey, utilizing 102 distinct color bands to map hundreds of millions of galaxies and more than 100 million stars. Through the wealth of data collected, researchers around the globe will gain vital information regarding cosmic inflation, the evolution of galaxies, and the origins of water and organic materials among planetary systems.
Precision Optics for Spectacular Results
At the heart of SPHEREx is VIAVI's cutting-edge optical components, which significantly enhance the spectrometer's ability to capture even the faintest infrared signals. This capability is essential for generating an accurate and comprehensive spectral map of the universe. VIAVI has outfitted the instrument with six precision 2k x 2k detectors, and their advanced Linear Variable Filters effectively separate wavelengths of light ranging from 0.75-5.0µm. Alongside this, VIAVI's sophisticated dichroic beamsplitter skillfully separates incoming light — reflecting certain wavelengths while transmitting others.
Celebrating Collaborative Achievements
Luke Scrivanich, Senior Vice President and General Manager, Optical Security and Performance, remarked on this milestone: "Our collaboration with JPL and Caltech has involved overcoming various technical challenges to push the boundaries of excellence in our precision optical filters. We extend our heartfelt congratulations to the teams at NASA, JPL, and Caltech for their incredible dedication and innovation."
Building on Past Accomplishments
The design of the SPHEREx spectrophotometer builds upon VIAVI's successful contributions to prior space missions integrating Linear Variable Filter technology. These contributions include critical instruments like the LEISA instrument on the New Horizons mission, which provided invaluable spectral imaging of Jupiter and Pluto, as well as the OVIRS instrument for the OSIRIS-REx mission that explored the asteroid Bennu's surface.
Future Prospects with SPHEREx
Additionally, the design is rooted in VIAVI's ongoing commitment to supporting space endeavors, exemplified by the MISE instrument on the Europa Clipper mission, aimed at mapping the surface ice on Jupiter's moon Europa. These advancements affirm VIAVI’s significant role in space exploration and the technological innovation that accompanies such ambitious undertakings.
