Use Cases

DKIST solar telescope

The Daniel K. Inouye Solar Telescope (DKIST) is the world’slargest solar telescope.

The design and manufacturing of its 4.2m diameter primary mirror and its surrounding cell has been awarded to the company AMOS.

As a subcontractor to AMOS, Micromega has designed and manufactured the 142 hydraulic and pneumatic actuators that continuously correct the shape of the thin primary mirror to an accuracy better than 45 nm RMS.

The cell was integrated and tested in the telescope in 2017. In January 2020, the Daniel K. Inouye Solar Telescope unveiled the most detailed images ever taken of the surface of our sun.
