Nothing can hide! Gain the upper hand in any hunting or tactical situation with the powerful target detecting ability of the Armasight® Helios 640 HD HD 4-32x100mm (30Hz) Thermal Imaging Bi-Ocular. Based on the latest FLIR Tau 2 VOx microbolometer core, the Helios detects targets through snow, rain, dust, smoke, fog, haze and other obscurants to give you the targeting advantage in any environment. The Helios 640 HD is effective day or night, delivering true 24/7 performance for hunting and tactical ops.

The Helios is the lightest and most compact thermal imaging bi-ocular in its class, and is ideal for sustained viewing and improved depth perception in the field. Operation is simple, thanks to an easy and intuitive drop-down user interface and smartly engineered controls.

Rapid start-up gets the Helios up and running in less than 3 seconds, and a full compliment of color modes and special, user-adjustable imaging tools allows for fine tuning images to the situation and operator preference. Brightness is adjustable to 8 levels, and a video out jack allows for recording and playback with the optional Armasight DVR (sold separately).

Special User-Adjustable Imaging Tools provide ultimate versatility and customization.

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 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 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 Helios models allow for user to manually trigger or interrupt scheduled UCMNUC/FFC function.

Silent Shutterless NUC TM (SSN) In addition to user controlled manual NUC/FFC all Helios 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 an always ON enhancement.
