Optical Lenses Of Landing Cameras Using Titanium Alloy Light Materials Such As Chang'e 4
Jan 26, 2019

On January 8th, it was revealed on the investor interaction platform that the No. 3 and No. 4 adopted the landing camera optical lens manufactured by Yongxin Optical.

Yongxin Optical said that the space environment has very high requirements for the lens, and it must withstand the acceleration of the rocket taking off, the space radiation, and the extremely cold and extremely hot vacuum environment. The manufacturing team has undergone countless tests in each process from design, material selection, processing and assembly. Titanium alloy lightweight materials are used for processing and surface treatment, radiation-proof optical glass applications, and air pressure changes to the air layer. The handling of gas, the guarantee of coaxiality between multiple lenses, etc., the technical difficulty of each process is very large. (Source: SoTi.)
