Shvabe patented telescope lenses
Shvabe Holding, part of Rostec Corporation, has received a patent for an apochromatic lens, a useful optical model that improves astronomical telescopes and increases the competitive advantage of the enterprises’ production.
The new model, designed for the field of optical instrumentation, can be used for astronomical telescopes, according to the press service of the company. The apochromatic lens consists of three complex systems of biconcave, convex-concave, and lenticular lenses.
The new product will reduce the length of lenses while maintaining high image quality.
The lens is made of conventional optical glass from four different brands. The refraction and dispersion indices for the first, second, and fourth lenses are the same.
