ALMA Telescope

What is the ALMA-Project?

The Atacama Large Millimeter Array (ALMA) is located 5000 meter above sea level in the Atacama Desert (Chile). It is a giant telescope that consists of 66 moving high-precession antennas.

These can be interconnected to one efficient telescope with a diameter of up to 16 kilometer and astronomical observations in the radio band millimeter- and submillimeter are made of.

The ZRINSKI GmbH is integrated in this project for several years and is responsible for the production of the mirror coating of more than 25 antennas.

One antenna consists of 264 aluminum panels. Each of these high-precision panels is milled of an 80 kilogram weighing aluminum block. The accuracy of these panels amount eight-one-thousandths of a millimeter. It was a technical challenge for the company to hold this precision over a production period for several years.

Such tasks can only be solved if one has the appropriate technology, know-how and skilled and motivated employees. The subsequent participation in other telescope projects, such as APEX (Atacama Pathfinder Experiment) and SPT (South Pole Telescope) confirms our quality and precision.

With ALMA, cold molecular gas and the last reverberation of the Big Bang can be observed. Therefore ALMA can help the astronomers to analyze the origin of planets, stars, galaxies and even the universe as a whole.
