Motion Control Application – Searching for “Dark Energy”!
Motion control Application- The HETDEX project is the first major attempt to find “dark energy” in the universe. With special spectrographs, the three-dimensional positions of one million galaxies are recorded. In the summer of 2012, the Hobby-Eberly Telescope started scanning the universe – aided by maxon motors every step of the way.

Taunton, MA — Motion Control Application – The Hobby-Eberly Telescope (HET) is located at the McDonald Observatory in West Texas. Its spherical primary mirror consists of 91 identical hexagonal segments, each one meter in size. Together, these individual mirror segments form a mirror with a diameter of almost 11 m, which makes it the largest in the world. The effective aperture of the primary mirror currently amounts to 9.2 m at an opening angle of four arc minutes*.
