Located in Hawaï, the Daniel K. Inouye Solar Telescope revealed unprecedented details of the Sun’s surface. Its entry into service opens up a new era for solar science and should allow a leap forward in the understanding of the Sun and its impacts on our planet. One of the key elements of the telescope, the primary mirror cell, has been designed and manufactured in Belgium by AMOS, Agoria member.


The National Science Foundation (NSF), the National Solar Observatory (NSO) and AURA1 just released DKIST’s first images!

With a primary mirror of 4.2 m in diameter, DKIST – formerly called Advanced Technology Solar Telescope (ATST) – is gigantic compared to the other solar telescopes. It is packed with complex technologies in order to capture very detailed images of the Sun’s constantly-changing surface with a resolution twice better than former solar observatories.

One of the key elements of the telescope, the primary mirror cell, has been designed and manufactured in Belgium by AMOS. The unprecedented resolution of these images demonstrates the power and precision of this new telescope.

Un des éléments clés de ce télescope, la cellule du miroir primaire, a été conçu et fabriqué en Belgique par la société liégeoise AMOS. La résolution sans précédente de ces images démontre la puissance et la précision de ce nouveau télescope.

Philippe Gilson, AMOS’ CEO, stated: "With this project, AMOS demonstrates its expertise in the field of large solar telescopes, in addition to its extensive track record in the field of astronomical telescopes. Each project in this domain is a new technical challenge that the AMOS teams take successfully, thanks to their passion and expertise.

AMOS in a few words
Located in Belgium, AMOS has been designing and building high-precision optical and mechanical
equipment for more than 35 years. Its main achievements are professional telescopes, space optical
systems, test equipment for space instruments, and high-precision mechanical equipment. It employs
more than 100 employees highly skilled in advanced technologies and offers services to the space
industry, to the professional astronomy sector, to scientific laboratories and to industry.
AMOS has customers in Europe (ESA, ESO, AIRBUS DEFENCE & SPACE, THALES ALENIA SPACE, OHB), in
United States (AURA), in India (ISRO, PRL, ARIES), and has more recently expanded its business in
countries like China, Turkey and Russia.
