The Novosibirsk plant of the Shvabe holding will begin serial production of the Newton telescope. It is claimed that the device is an exact replica of the original reflector, created by the great scientist in 1668.
The first lens telescope is considered to be a refractor telescope, which was developed by Galileo Galilei in 1609. However, this device produced a low quality image. In the mid-1660s, Isaac Newton proved that chromatism was the cause of the problem, which could be eliminated by using a spherical mirror instead of convex lenses. As a result, in 1668, Newton's telescope was born, which made it possible to bring image quality to a new level.
A replica of the device created in Russia received the designation TAL-35. According to the Shvabe holding, the drawings of the telescope were created almost from scratch based on available information.
The design of the device turned out to be simple: it is a spherical support (mount) and an optical tube divided into two parts - the main and the movable.
“TAL-35 is an exact copy of the historical original. The only difference is the image quality. If Newton used a polished bronze plate for reflection, then the replica was equipped with an optical mirror treated with aluminization. Thus, despite the souvenir purpose, these telescopes can also be used for observations,” the creators say.
