Armasight by FLIR Prometheus-C is the latest and most technologically advanced Thermal Imaging monocular to enter the sporting, law enforcement, and military markets.

The Prometheus-C is a solid state, uncooled, long-wave infrared, magnified, dedicated handheld thermal imager intended for day and night engagements. The Prometheus-C is based on the FLIR Tau 2 VOx microbolometer core. The thermal imaging technology allows you to detect targets by cutting through snow, dust, smoke, fog, haze, and other atmospheric obscurants. The Prometheus-C demonstrates its operational flexibility for all mission applications.

An additional Armasight proprietary hyper-image processing (HIP) code provides the Prometheus-C with a robust library of software features to tailor the image to the optimum standards required by the operator. The nine-pin connector on the Prometheus-C reveals the dynamic nature of this mite-sized powerhouse. Through the multi-pin connector, the operator can record video using the Armasight Digital Video Recorder (DVR) or augment the battery life by attaching to external battery options.

  • Special User-Adjustable Imaging Tools
  • Active Contrast Enhancement (ACE) – a digital “Contrast” correction that allows for a smart scene optimization based on dynamic adjustments where a variety of contrast levels occur depending on relative scene temperature.
  • Second Generation Digital Detail Enhancement (DDE) – a “Sharpness” correction that is digitally enhances the picture to present clearer imagery, significantly improves edge sharpening and further reduces image noise.
  • Smart Scene Optimization (SSO) – a fine-tuning computational correction that significantly improves an overall visual acuity for targets that have thermal signatures similar to a surrounding background.
  • Automatic Gain Control (AGC) – a “Gain” correction that used to automatically adjust the gain to an appropriate range, the weaker the image signal, the stronger the gain.
  • User-Controlled Manual Non-Uniformity Correction/Flat-Field Correction (UCMNUC/FFC). There is a mechanical shutter between the camera sensor and the lens. This shutter is used to perform a non-uniformity correction (NUC) also known as flat-field correction (FFC. During FFC, 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, resulting in a more uniform image after the process is complete. All Prometheus-C models allow for user to manually trigger or interrupt scheduled UCMNUC/FFC function.
  • Silent Shutterless NUC ™ (SSN) – In addition to user controlled manual NUC/FFC all Prometheus-C models employ a digital supplemental non-mechanical flat-field correction that allows to extend the periods between mechanical shutter events and to further reduce image noise. SSN is always ON enhancement.
