Twelve large missile carriers carrying the “Dongfeng – 5C” liquid intercontinental strategic nuclear missile came in, and tens of thousands of spectators cheered at the scene. Behind the cheering was the confidence of a nation and t…

On Tiananmen Square, the light of new weapons and equipment comes not only from metal shells, but also from those sophisticated optics System, they are quietly changing the rules of the future battlefield. On September 3, 2025, the military parade co…

All departments and staff of the company: September 3, 2025 is the 80th anniversary of the victory of the Chinese People’s War of Resistance against Japanese Aggression and the World Anti Fascist War. In order to remember the history, remember …

The core of modern science and technology is really inseparable from that small chip. The most delicate and critical steps in chip manufacturing are probably photolithography and etching Has. These two technologies are like a pair of tacit sculptors.…

In the high-tech field, quartz glass has become an indispensable material due to its excellent performance, but its metallization process faces a thorny problem: how to make the metal layer resistant to corrosion in harsh environments and ensure the …

The optical probe with a diameter of only one thousandth of the hair can accurately identify defects of 0.3 microns, which is like finding a pepper on a football field. Behind this seemingly ordinary instrument is a breakthrough in optical techn…

In the extreme environment of aerospace optical window, a 0.1mm gap between a piece of K9 glass with a diameter of 30cm and the titanium alloy frame is enough to cause the failure of the whole satellite in orbit. This seemingly small interface is a p…

A piece of glass with a thickness of only 30 microns (0.03mm), which is a quarter thinner than A4 paper, can withstand more than 1 million times Bend without breaking. This achievement, which seems to violate the common sense of materials, is quietly…

As a material widely used in modern science and technology, quartz glass has occupied an important position in many fields with its excellent optical properties, thermal stability and chemical corrosion resistance. Especially in precision instruments…

Photoelectric materials are an indispensable part of modern science and technology, and are widely used in many fields such as display technology, solar cells, laser equipment and sensors. In these applications, etching technology, as an important pr…
