The Armasight Prometheus 336 2-8x25 (30 Hz) Thermal Imaging Monocular is an advanced thermal imaging monocular for sporting, law enforcement, and military applications. It features a FLIR Tau 2 VOx microbolometer core. The Prometheus can be used 24/7 in any lighting. Thermal imaging technology allows the use to see through snow, dust, smoke, fog, haze, and other atmospheric obscurants. The Prometheus thermal imager is extremely difficult to detect with other devices, as it emits no visible light or RF energy.The Prometheus is a solid state, uncooled, long-wave infrared, magnified, dedicated handheld thermal imager intended for day and night engagements.

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. This allows you to fine tune how the heat is visualized for a wide variety of temperatures.

Second Generation Digital Detail Enhancement (DDE)
This is a “Sharpness” correction that digitally enhances the picture to present clearer imagery, significantly improves edge sharpening and further reduces image noise. This makes the outlines of living things cleaner and easier to distinguish.

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. For example if it is 98 degrees outside and you are looking for a person, this will visualize those subtle differences.

Information-Based Histogram Equalization (IBHEQ) 
This is an 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 Prometheus 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 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.
