Infrared monocular - Armasight Prometheus Mini

The Prometheus Mini is Armasight's latest hi-tech solution among hand-held tactical thermal imaging devices. It was designed to be as compact and lightweight as possible, while retaining the highest possible quality, technical parameters and functionality.

  • Display


    800x600 OLED

  • Zoom


    2×, 4×, 8×

  • Work time

    Operation time of the infrared monocular

    up to 2.5 h

  • Waterproof


Infrared monocular - Armasight Prometheus Mini greatly facilitate observation of scenes and allow to detect and identify objects at very long distances. The Prometheus Mini can operate both during the day and at night, ensuring visibility in any kind of weather conditions. It does not utilise additional IR illuminators and does not emit any electromagnetic radiation, which makes it undetectable for other devices.

Key features of Infrared monocular - Armasight Prometheus Mini

  • 800x600 OLED display
  • 2×, 4×, or 8× digital zoom
  • advanced image processing technologies: Digital Detail Enhancement™, Active Contrast Enhancement™, Smart Scene Optimization™, Silent Shutterless Non-uniformity Correction™
  • video output allowing to connect a recorder
  • built-in compass and inclinometer

The video output allows to connect the device to an Armasight DT digital recorder and to record video material in PAL/NTSC format. It makes Prometheus Mini a perfect choice for tactical operations conducted by military, police, or special forces,, as well as for demanding civilian users. A versatile and miniature thermal imaging monocular, Armasight Prometheus Mini will perform in any conditions.

Advantages of thermal imaging monocular

  • Sensor


    The thermal imaging monocular is based on a uncooled microbolometer sensor FLIR Quark 2 (17-micron pixel Uncooled VOx Microbolometer), a product of a company recognized as a leader in thermal imaging technology.

  • Sensor


    Thermal imaging utilises heat radiation – any object with temperature above the absolute zero emits infrared radiation. Spectral analysis of this radiation allows to measure the temperature very accurately at long distances, and to prepare graphic representation of spatial distribution of temperature. Even the smallest of changes are recognized and can be converted into images.

  • Sensor


    Thermal imaging devices can be used effectively in any lighting conditions (unlike night vision devices, which require a certain level of ambient light, or rely on external IR illuminators) or weather – they are not affected by precipitation, or presence of dust or smoke in observed area.

  • Specialist software


    Additionally, Hyper-Image Processing (HIP) software grants the user access to advanced image processing functions and allows to adjust them to current needs.

  • Construction


    Compact construction, small size, and weight of just 230 grams allow to conceal the Prometheus Mini with ease, e.g. in a pocket, a backpack, or attached to a tactical vest. It will not hinder the user's mobility. Moreover, the device comes with a built-in compass and inclinometer – tools allowing the user to quickly calculate a target's location and the distance to it.

  • Specialist software


    The Prometheus Mini is offered in variants with either a 336×256 (refresh rate 9, 30 or 60Hz), which allows the user to pick an optimal solution, smoothness- and quality-wise.

  • Waterproof, durable housing


    The infrared monocular's housing complies with strict MIL-STD-810(G) norms, guaranteeing water resistance for up to 20 meters. These features make it a perfect solution for demanding users and professional outdoor applications.

  • Remote control


    Included remote control greatly facilitates the operation of Prometheus Mini thermal imaging monocular.

  • Changeable display modes


    Changeable display modes: white - hot, black – hot, variable colour patterns.

  • Energy-efficient


    Efficient power management allows the infrared monocular – powered by either a CR123A battery or a 16650 rechargeable battery (charger included) – to operate continuously for up to 1.5 or 2.5 hours respectively. It is also possible to use an external power source – optional Armasight Extended Battery Pack (for 4x CR123A or 16650 batteries).

  • Waterproof housing


    Made in CNC technology, it allows to comfortably operate the monocular in any weather conditions – snow, rain, or fog.

  • Intuitive operation


    User-friendly drop-down menu, and 3 function buttons.

  • Very short switch-on time


    The Prometheus Mini monocular is ready to work within 3 second from switching on!

  • Designed and made in the USA


    Armasight, the device's manufacturer, guarantees complete reliability and excellent technical parameters of their wares.

Advanced image processing functions

  • Active Contrast Enhancement (ACE) based on dynamic change of settings, depending on ambient temperature.
  • Second Generation Digital Detail Enhancement (DDE) – digital sharpness correction to produce clearer images with more pronounced edges and reduced noise.
  • Smart Scene Optimization (SSO) – precise adjustment of image parameters, improving overall visibility of objects of thermal signatures similar to ambient temperature.
  • Information-Based Histogram Equalization (IBHEQ) – an enhancement utilising an environment dependent algorithm automatically adjusting camera gain in order to exclude pixels not containing critical information; especially useful during observation of uniform scenes, such as sky and large bodies of water, to improve visibility of objects against their background.
  • User-Controlled Manual Non-Uniformity Correction/ Flat-Field Correction (UCMNUC/ FFC) – non-uniformity correction, or flat-field correction. The shutter presents a uniform temperature source to each detector element in the array. While imaging the flat-field source, the camera updates the offset correction coefficients, allowing to obtain a more uniform image. Operation controlled manually.
  • Silent Shutterless NUC™ (SSN) – In addition to manually operated NUC/FFC, the device employs a supplemental flat-field correction to further reduce image noise.
