VIAVI Solutions Inc. announced on January 7, 2025, its contribution to NASA's Europa Clipper mission, which launched on October 14, 2024. Leveraging its expertise in precision thin film optical coatings, VIAVI supplied a precision order sorting filter for the Mapping Imaging Spectrometer for Europa (MISE) instrument aboard the spacecraft. The Europa Clipper mission is set to begin orbiting Jupiter in April 2030.
The MISE instrument is vital for analyzing the surface composition of Jupiter's moon Europa, aiming to determine the habitability of its subsurface ocean. VIAVI's precision order sorting filter ensures the optimal performance of MISE, enabling it to capture high-resolution spectral data in the infrared range from 0.8 to 5 micrometers. This filter combines photolithographically-patterned bandpass filters, a Linear Variable Filter (LVF), and assembled optics.
VIAVI collaborated with NASA to address technical challenges in developing this unique filter, including the slope of wavelength progression, co-planarity of the assembled optic, and placement of LVF center wavelengths. Luke Scrivanich, Senior Vice President and General Manager, Optical Security and Performance, VIAVI, stated that the team's dedication to precision engineering met the stringent requirements for space exploration instruments like MISE.
