Overview

The Prometheus Pro line of high performance handheld magnified thermal monoculars 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 Prometheus Pro handheld thermal monocular exhibits the same 20/50 gold standard performance as the Zeus Pro and Apollo Pro. The Prometheus Pro can withstand immersion to 20 meters and absorb the most brutal environmental shocks typically associated with heavy caliber shooting. Based around a common cores of electronics, signal processing, and lens interfaces, a version of the Prometheus Pro can be ordered to meet virtually any requirement for an affordable uncooled magnified thermal monocular. Utilizing the latest FLIR TAU-2 Technology, the Prometheus Pro is offered in 336x256 or 640x512 pixel formats. These options are further enhanced by professional militarygrade 30mm, 50mm, 100mm Germanium (Ge) objective lenses creating a wide variety of optical magnifications and range performance capabilities that the customer can select from. Armasight has introduced a unique dual battery option for the Prometheus Pro Thermal Monocular consisting either of four 3.0VDC 123A batteries all oriented in the same direction to prevent confusion in replacement, or four 1.5VDC AA batteries preloaded in a cartridge. In a pinch, a single 123A 3.0VDC battery can power the Zeus Pro for just over one hour. The Prometheus 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 Prometheus Pro uses a 9-pin multipin 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 Prometheus Pro. The Prometheus 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 Prometheus Pro is the ideal tool for scouting and target detection where the ambient environment is oriented for concealment. The Prometheus Pro is also an extremely useful tool for viewing scenes through environmental obscurants such as smoke, haze, fog, or dust. The Prometheus Pro marks the pinnacle of Armasight’s handheld uncooled thermal imaging family of products.

All Armasight thermal imagers are based on FLIR Tau 2.7.2 or later cameras that allow to improve overall image quality in a wide range of dynamic thermal environments, the imagers has employed special user-adjustable imaging tools that include:

• 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.

• 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 Armasight thermal imagers 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 Zeus 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.
