SAFETY SUMMARY
• Read and follow all instructions
• Read all warnings
• Only use the attachments/accessories specified by the manufacturer
• All service must be provided by the manufacturer
WARNING:
DO NOT DISASSEMBLE THE DEVICE. Disassembly can cause permanent damage.
WARNING:
This product contains natural rubber latex which may cause allergic reactions! The FDA has
reported an increase in the number of deaths that are associated with an apparent sensitivity to natural
latex proteins. If you are allergic to latex, it is a good idea to learn which products contain it and strictly
avoid exposure to those products.
CAUTION:
Use of controls or adjustments or performance of procedures other than those specified herein may result
in hazardous radiation exposure.
CAUTION:
• Do not point the camera at high-intensity radiation sources such as the sun, lasers, or arc welders.
• Do not leave fingerprints on the camera’s infrared optics. Clean only with low pressure fresh water
and a lens cloth.
• Keep the equipment clean. Protect it from moisture, dramatic temperature drops, and electrical
shocks.
• DO NOT force the equipment controls past their stopping points.
• DO NOT leave the equipment activated during breaks in operation.
• DO NOT store the equipment with the batteries installed.
• Thoroughly clean and dry each item before placing them into the storage case.
NOTES:
• To avoid losing unsaved data, DO NOT remove the batteries or disconnect the external power
source while the Prometheus C is on.
• Inadvertent sun damage is not considered a defect in material or workmanship, and is therefore not
covered in the product warranty.

INTRODUCTION
1.1 PURPOSE OF EQUIPMENT
The Prometheus C is a solid state, uncooled, long-wave infrared, magnified, dedicated handheld thermal
imager intended for day and night engagements. The thermal imaging technology allows you to detect targets
by cutting through snow, dust, smoke, fog, haze, and other atmospheric obscurants. The Prometheus C
demonstrates its operational flexibility for all mission applications.
Its proprietary hyper-image processing (HIP) gives the Prometheus C a robust library of software features
to tailor the image to the needs of the mission. Plus, the operator can record video using the Digital Video
Recorder (DVR) or augment the battery life by attaching to external battery options.
Unlike the use of laser targeting or near-infrared illumination to augment night vision equipment, the
Prometheus C thermal imager is extremely difficult to detect with other devices, as it emits no visible light or
RF energy.
The Prometheus C is available in different versions, with 1x or 2x optical magnifications. Prometheus C series
also provides up to 8x digital zoom for models based on 640x512 cores and up to 4x digital zoom for models
based on a 336x256 core.
The Prometheus C is powered by two CR123A (2×3V) batteries. The Extended Battery Pack or 6VDC/ 600mA
power source can also be used to power the Prometheus C.
The Prometheus C is equipped with a standard NTSC/PAL video input/output function that makes it possible
to connect to an external video display or monitor, or to record thermal images for field documentation or
training purposes. It also allows the transmission of data from one remote display to that of the Prometheus C.
The Prometheus Can be used in conjunction with other equipment such as the Digital Video Recorder or
Extended Battery Pack.
Extremely reliable and versatile, the Prometheus C is a highly useful thermal imaging system.

DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The Prometheus Consists of next primary parts: a body, a lens assembly and an eyepiece assembly.
The Prometheus C is a thermosensitive device. It senses the differences in heat emitted by objects in its
field of view, and converts the received temperature pattern into a viewable image that represents the
scene in contrasting black & white or color patterns, depending on the user’s selected image palette.
FIGURE 2-1. PROMETHEUS C THERMAL IMAGING MONOCULAR
NOTE:
It is important that the Prometheus C sensor receive sufficient thermal contrast between the target
and background area, or between the different parts of a target. For example, the vast temperature
contrast between the snow and any heat target (such as an animal) makes it very easy to distinguish
the target.
The main optical-electronic components of the Prometheus C include: an objective Germanium thermal
lens, eyepiece, a thermal-imaging camera, a display, a control card, and a button control panel.
The Prometheus C is equipped with manual eyepiece and objective lens focusing.

ARMASIGHT by FLIRPROMETHEUS C USER MANUAL
To accommodate individual user needs, the Prometheus C has a variety of digitally controlled options
such as:
• Display Brightness
• Digital Zoom
• Palette Color Selection
• User-Controlled Manual Non-Uniformity Correction/ Flat-Field Correction (UCMNUC/ FFC)
• Imaging Enhancements
• Custom Settings
All Prometheus C devices are based on FLIR Tau 2.7.2 or later cameras that allow for improvements in
overall image quality in a wide range of dynamic thermal environments. The Prometheus C has employed
special user-adjustable imaging tools that include:
•Active Contrast Enhancement (ACE) – a digital “Contrast” correction that allows for 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, significantly sharpens edges, and further reduces image noise.
•Smart Scene Optimization (SSO) – a fine-tuning computational correction that significantly
improves overall visual acuity for targets that have thermal signatures similar to the 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 C 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 C models employ a digital, supplemental, non-mechanical flat-field correction that
extends periods between mechanical shutter events and further reduces image noise. SSN is an
always ON enhancement.
Information on the current operating state (battery status, active function in the display etc.) is
continuously displayed, making field operation of the Prometheus C simple and convenient.
Manufactured for exceptional durability, the Prometheus C has a lightweight and robust aluminum body.
The Prometheus C can be mounted to a tripod with 1/4’’ threaded socket located on the body of the
device.

10 ARMASIGHT by FLIRPROMETHEUS C USER MANUAL
A standard NTSC/PAL video input/ output connector enables an external video display (monitor/ TV) or
video recorder to be connected to the Prometheus C. An external 6VDC/600mA power source can also be
connected to the Prometheus C.
The Prometheus C is powered by two CR123A (2×3V) batteries.
Figure 2-2 shows the Prometheus C. The ITEM NO. column of Table 2-1 indicates the number used to
