Kazan enterprise has patented optics with increased reflection
Specialists of the Kazan NGO "State Institute of Applied Optics" (NPO HYPO), which is part of the Shvabe holding of Rostec State Corporation, have patented a new solution to increase the reflection coefficient of an optical mirror in all operating spectral ranges. The technology can be applied in laser technology, according to a message on the state corporation's website.
In the invention, a reflective layer of a mirror made of a film 200-400 nanometers thick, made of an alloy of aluminum and copper, was used. The protective layer is made of lutetium oxide with a thickness of 100-250 nanometers.
The report noted that the development can be applied as part of laser technology and optoelectronic devices.
"The reflection coefficient of the proposed optical mirror is 0.1–0.4 percent higher in the visible, medium and far spectral IR ranges than that of the prototype. In addition, gold, which is a precious metal, is used in the reflective layer of the prototype. Aluminum and copper used in the reflective layer of the proposed optical mirror are ten times cheaper," Rostec quoted Villen Baloev, Director General of NPO HYPO, as saying.
In December 2021, Rospatent reported that the Beber disinfection robot was among the top three patented inventions of the year.
