The Armasight Helios HD is a high-tech, powerful and high-quality thermal imaging device based on the latest FLIR Tau 2 VOx microbolometer core. The Armasight Helios line consists of different models, so you will have an opportunity to choose the most appropriate for you variant.
This thermal imaging bi-ocular system is full of advantages which you will be able to estimate during your operations. The easy and intuitive drop-down user interface makes this device so user-friendly. The amount of color modes will give you a possibility to choose the most comfortable variant for you. The Armasight Helios HD is provided with video output function and you have an opportunity to get optionally a recorder. If you prefer to stay nearly invisible at night, you will be able to know that this device is extremely difficult to detect as it doesn’t emit any visible light or RF energy. You can be sure that you will be able to detect your target even under the most trying situations as this device can withstand difficult weather conditions such as temperature extremes and precipitations and still provide you with a high-quality image. The Armasight Helios will provide you with up to 4 hours of operation, and you can also optionally get extended battery pack to make your observation sessions even longer. Even the most demanding professionals will admit the advantages of this device.

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 HD 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 HD 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.
