Shvabe has been granted a patent for the apochromatic athermal lens. Designed by the specialists of the Holding, this is an optical instrument for aerial photography.

The new device is compatible with modern 0.4- to 1-µm radiation detector arrays and capable of operating at temperatures from +/-60 °C. The lens offers an angular field of not less than 19°, a focal distance of 300 mm, and an aperture ratio of 1:4.5.

The lens was developed at the Zverev Krasnogorsk Factory of the Holding. According to Vadim Kaljugin, the Director General of the factory, this new product offers significant advantages over other similar Russian and foreign products.

"The device   produces high-contrast images in the 0.4- to 1-µm spectral band. In comparison, the most advanced similar device operates in the 0.6- to 1-µm band. Moreover, our product is athermal within a wide range of working temperatures, which is also an important factor for aerial photography at a height of several dozens of kilometers." Vadim Kaljugin stated.

Working on the design of this product, Shvabe specialists offered and patented two options for the optical system of the new lens. According to a press release from the Holding, the key parameters of both options meet the technical specifications and will be used for further developments.
