CILAS Enhances Flight Mirrors and Diffraction Gratings for ELOIS Hyperspectral Instrument

CILAS, a leading provider of high-performance optical coatings, has achieved a significant breakthrough in the field of hyperspectral imaging. The company successfully applied an enhanced silver coating to flight mirrors and diffraction gratings manufactured by AMOS for the ELOIS hyperspectral instrument.

This advanced coating significantly enhances the performance of the optics, paving the way for improved image quality and data acquisition capabilities.

Integration of Enhanced Optics into First Flight Model of Compact Hyperspectral Imager

Following the successful application of the enhanced silver coating, AMOS is now integrating these optics into the first flight model of their compact yet powerful hyperspectral imager. The imager will be deployed on the InnoSat platform from OHB Sweden AB as part of the European Commission Horizon2020 IOD/IOV initiative, conducted in collaboration with the European Space Agency (ESA) and funded by the European Union. This integration marks a crucial step in the development of the instrument, positioning it for a groundbreaking In-Orbit Demonstration mission scheduled for early 2025.

Paving the Way for Future Hyperspectral Constellations

The successful application of the enhanced silver coating and the integration of these optics into the first flight model of the ELOIS hyperspectral imager signify a major advancement in the field. This achievement not only enhances the performance of the instrument but also paves the way for future hyperspectral constellations. The upcoming In-Orbit Demonstration mission, conducted in collaboration with ESA, will showcase the capabilities of the ELOIS instrument and provide valuable insights for the development of future space-based hyperspectral imaging systems.

This mission, funded by the European Union, holds great promise for advancing our understanding of the Earth’s surface and supporting a wide range of applications in environmental monitoring, agriculture, mineral exploration, and disaster response.


In conclusion, CILAS’s successful application of an enhanced silver coating to flight mirrors and diffraction gratings for the ELOIS hyperspectral instrument represents a significant breakthrough in the field of hyperspectral imaging. This achievement, combined with the integration of these optics into the first flight model of a compact hyperspectral imager, sets the stage for a groundbreaking In-Orbit Demonstration mission scheduled for early 2025. The advancements made by CILAS and AMOS not only enhance the performance of the ELOIS instrument but also pave the way for future hyperspectral constellations.

CILAS will be present at Milipol 2023, Hall 5 / Stand F179.
