TEC

Telescope Engineering Company, better known as TEC, is located in the US state of Colorado. Yuri Petronin, the company's president, produces apochromats of the top class.

Since 1994, the company has been producing high-end refractors for science and research as well as for public institutions and dedicated amateur astronomers.

As customers requested, TEC has started to offer astronomical binocular telescopes or "binoscopes". Such instruments offer an extrordinary usability and functionality for visual astronomy. The well-known advantages of binocular viewing can be found in perfection here.

The optics calculated in-house meet the highest quality standards. Likewise, the mechanical components are manufactured with the aim of perfection in their own home. Read more about the advantages of oil-spaced lenses for apochromatic triplet objective by TEC.
