Operational Use
The lens's fixed focal length provides the highest magnification and operators would utilize this sensor for viewing:
• subjects at long range and examine for detail in color
• subjects at night using the low-light camera
• laser illuminated subjects at night
• subjects obscured by haze using the XLP filter
For normal daylight conditions (visible wavelengths 400-700 nm), operators would use the higher magnification of
the EON sensor to examine a subject they had first located using the EOW sensor. If the subject moves out of the
EON sensor's view, the operator would switch back to the EOW sensor to re-acquire the subject.
At night, operators would select the LP filter to switch to the low-light camera and view a wavelength band of 450-
950 nm. If equipped in the turret, operators could view a subject highlighted with a laser illuminator because the
laser's wavelength corresponds to the wavelength band of the low-light camera. Otherwise, operators would need
night vision goggles to view any laser illuminated subjects.
In haze conditions, operators would select the XLP filter to restrict the view to a wavelength band of 840 to 1000 nm.
This filter minimizes the impacts of haze and improves the performance of long range viewing.
Operating Temperature Limits
The EON sensor is exposed to temperature fluctuations that occur inside the gimbal. The system monitors the
sensor's temperature and protects it from thermal extremes. The sensor will only be operational within the following
temperature control limits:
• For cold operation, the sensor will shutdown below -55°C and not restart until -45°C.
• For hot operation, the sensor will shutdown above 70°C and not restart until 60°C.
• For cold starts below -45°C, the sensor will not operate until it has been warmed.
Operator's have the capability to control the following imaging parameters:
• Sensitivity
• Level
• Scene Setup
• Filters
• Initiate a BIT
