The world`s largest astronomical telescope lens is made of nickel-aluminum-silicon alloy

2018-12-24

According to a recent report by the US [Advanced Materials and Process Technology" magazine, the larger astronomical telescope project jointly developed by the United States, Italy, and Germany uses nickel-aluminum-silicon-alloyed materials to make lenses more clearly visible. The application of optical and Researchers at the Fraunhofer Institute for Precision Engineering provided this report. The new aluminum-silicon alloys are designed to meet the thermal expansion coefficient of nickel and can be used to fabricate very stable lightweight structures.

The use of such nickel-aluminum-silicon alloys to manufacture Lasso lenses is the last application and innovation of optical components. The two lenses have a diameter of 8 meters and a resolution of 23 meters.
