Прецизионные методы контроля в точном оптическом производстве ОКБ «АСТРОН»

Precision control methods in ASTROHN Technology Ltd precision optical production

The author of this saying is unknown but it is clear that this person was directly related to production. It reads: “I can do what I can measure.” In precise optical manufacturing, precision control methods are of paramount importance. However, it is not enough to have reliable high accuracy metrological equipment. To maintain reproducibility of the results, it requires regular calibration and verification. To do this, we use the services of authorized organizations and apply reference calibration samples for each [...]

Изготовление и аттестация асферических поверхностей

Production and certification of aspherical surfaces in ASTROHN Technology Ltd

As is known, no modern high-tech optical system can do without aspherical elements. The manufacture and certification of aspherical surfaces are the most time-consuming and, therefore, limiting stages of the process. Our equipment provides high-precision aspheric grinding with a spherical diamond tool with an accuracy of 1 µm PV and polishing with a pneumatic membrane tool with a polyurethane working part. We always strive to optimize processes to provide our customers with thermal imaging cameras on time and at the best [...]

The specialists of ASTROHN Technology Ltd have developed a series of antireflection coatings for optical parts

The specialists of ASTROHN Technology Ltd have developed a series of antireflection coatings applied on the surface of optical parts by evaporation in vacuum. To develop optical devices operating in the middle infrared range (λ = 3–14 μm), materials are used with high refractive indices (for germanium nλ=4,00, for silicon nλ=3,50, for zinc selenide nλ=2,5), which causes a number of certain difficulties. One of the most basic problems is the high reflection from one surface of the optical part (the [...]

Оптико-электронный комплекс мобильного базирования АСТРОН-4К

ASTROHN-4K mobile based optical-electronic complex

In 2019, the specialists of ASTROHN Technology Ltd launched the serial production of the gyrostabilized 3-spectral mobile-based optical-electronic complex. The complex contains a high-sensitivity color TV camera with a wide zoom range, a high-speed far-infrared thermal imaging camera, and an active-pulse near-infrared TV camera. The complex also includes an eye-safe high-frequency rangefinder. All optical channels of the complex complement each other and together provide high detection, recognition, and identification of various objects, while compensating for the organic defects of each [...]

ASTROHN Technology Ltd: car night vision device

The classic night active-pulse (AI) vision technology provides observation only of a remote illuminated area of space. AI vision technology is the only technology that helps overcome near-light exposure, blocks the ability to see distant objects with reduced transparency of the environment, especially in night conditions. For most applications, the classic AI vision technology is the most effective but it does not ensure the safety of driving vehicles, especially in bad weather and at night. Safe night driving requires the entire [...]

ASTROHN Technology Ltd develops the first Russian dual-spectral microbolometric receiver

ASTROHN Technology Ltd develops the first Russian dual-spectral microbolometric receiver

In 2016, ASTROHN Technology Ltd launched the production of domestic uncooled vanadium oxide microbolometric detectors with the spectral range from 7 to 14 μm. This range is typical for objects having temperatures close to the temperature of the human body. There are tasks that require the use of a thermal imaging spectrum of 3-5 μm — registering a flare of a rocket, detecting flying objects from a red-hot exhaust gas, etc. This range is characteristic of cooled thermal imagers. The [...]
