PNV-57E and its modifications are one of the most common and affordable night vision devices on the secondary market, today it is often used and modify airsoft players, hunters. These devices can be found in the museum at the plant. Producer - Lytkarinsky plant of optical glass. This device was originally intended for the crews of helicopters and armored vehicles, but it also had civilian versions. This article presents one of the variants of the super-aperture "Zonnar", intended for night vision goggles PNV-57E, belonging to the 1st generation of night vision goggles. I have already met 4 varieties of this scheme among night vision optics. It is authentically known that in Soviet and Russian night vision devices they were used as specially designed lenses (for example - 1, 2), and special versions of photographic ones (Jupiter-3, Helios-40-2).Įngineers paid special attention to the Zonnar scheme, which made it possible to design high-quality and compact super-aperture lenses. The most significant limitation of the use of these lenses - a very small back focal length - is practically overcome by eliminating the mirror in the design of modern cameras. Electro-optical converters of devices often have dimensions similar to camera matrices, therefore, NVD optics look very attractive for use in photography. Night vision devices are usually equipped with the fastest and most compact lenses. View of the lens block before adaptation.
