The Helios Pro high performance handheld magnified Thermal Bi-ocular take full advantage of the technology and advancements that Armasight has developed for its uncooled thermal weapon sight programs. Due to design concepts emphasizing shared sub-assemblies, the Helios Pro handheld thermal bi-ocular exhibits the same standard performance as the Zeus Pro and Apollo Pro. The Helios Pro can withstand the most brutal environmental shocks. Based around a common cores of electronics, signal processing, and lens interfaces, a version of the Helios Pro can be ordered to meet virtually any requirement for an affordable uncooled magnified thermal bi-ocular.
Utilizing the latest FLIR TAU-2 Technology, the Helios Pro is offered in 640x512 pixel format with professional military-grade 50mm Germanium (Ge) objective lens. Armasight has introduced a unique dual battery option for the Helios Pro Thermal Bi-ocular consisting either of four 3.0VDC CR123A batteries all oriented in the same direction to prevent confusion in replacement, or four 1.5VDC AA batteries pre-loaded in a cartridge. In a pinch, a single CR123A 3.0VDC battery can power the Helios Pro for just over one hour.
The Helios Pro Thermal Imager is characterized by its simple and intuitive controls, functions, and features that are layered among direct button adjustments, direct combination button functions, and electronic menu selections. Armasight has included all of the key bells and whistles found in the Zeus and Apollo Pro series devices including electronic compass and inclinometer. The Helios Pro uses a 9-pin multi-pin connector to provide video-in imagery, where there may be a need for map or rangefinder display overlays, and external power access. In support of these capabilities, Armasight offers an optional laser range-finder, external battery pack, multispectral laser and other accessories designed to attach on the MIL-STD-1913 rail of the Helios Pro. The Helios Pro has Bluetooth© wireless capability and can directly interface with most smart phones with the potential for engaging a series of current and future applications.
The Helios Pro is the ideal tool for scouting and target detection where the ambient environment is oriented for concealment. The Helios Pro is also an extremely useful tool for viewing scenes through environmental obscurants such as smoke, haze, fog, or dust. The Helios Pro marks the pinnacle of Armasight's handheld uncooled thermal imaging family of products.
- 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.
- Information Based Histogram Equalization (IBHEQ) – a "Sky/Sea" enhancement – information based environment dependent algorithm that automatically adjusts camera gain and excludes pixels determined to not contain critical information, specifically helpful in scenes with lots of sky or water.
- 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 Helios Pro 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 Helios Pro 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.
