PVS-14 Night Vision Monocular Gen 2+ IIT
The PVS-14C is a professional night vision monocular produced by the Canadian company GSCI, which uses Photonis ECHO IIT (image intensifier tubes) and 27mm optics with a clear image and f/1.2 aperture.
Night vision consists of three main parts, the quality of which depends on the overall performance of the device.
- Image intensifier tube (IIT)
- Body
- Optics (lenses)
IMAGE INTENSIFIER TUBE
Image intensifier tube is the most important part of night vision. When choosing, you should be aware that the differences in the specification and performance of individual tubes can differ significantly, so it is necessary to pay attention not only to the manufacturer or generation of the given tube, but also to the specific values that each tube has listed in its datasheet.
The tube used in this NVG is an army stock tube with no data sheet provided. The FOM of this tube is around 1500-1600.
FOM (Figure of Merit): Figure of Merit is simply the tubes Resolution (or line pair per mm) multiplied by it's SNR (Signal to Noise Ratio). FOM=LP/MM * SNR
BODY
When choosing night vision, you should be aware that many manufacturers do not make any of the night vision parts, they just put the IIT in the already purchased body.
GSCI has been manufacturing custom night vision bodies for over 30 years. The PVS-14 is the most widespread design that has been used by armies for the past 20 years or so. GSCI does not make the PVS-14 bodies from plastic, but from high-strength aluminum and brings several features that are not present in the standard PVS-14 bodies.
Manual Gain Control is a feature that give the user the ability to manually control the brightness of their system. This is accomplished by rotating a gain knob on the night vision system.
SSF (Stow Safety Feature): allows you to save energy during operation. Moving the device verticaly up turns the NVG off, and flipping back to eye level turns the device back on.
Adjusting objective lenses and eyepiece focus: you can adjust focus on the eyepiece and also on the front lens for close-up and distant objects.
The PVS-14C is powered by one AA battery (with AA extender attached) or one CR123 battery (without AA extender) with running time up to 40 hours.
The device has an external power port that allows the NVG to be powered using a USB cable.
LED Indicators:
- Flashing Red LED: IR Illuminator is on. You can be detected by another night vision device.
- Double flashing Red LED: Light overload! The device is exposed to bright light source. After 10 consecutive double flashes, the device shall turn itself off.
- Flashing Yellow LED: Indicates low battery.
OPTICS
The quality of the lenses is also an important parameter, as low-quality optics deteriorate the clarity and brightness, while reducing the overall efficiency of the device. An important parameter is the aperture number, which expresses the ratio of the focal length of the optical system to the diameter of the input lens. The lower the number, the better its brightness.
The PVS-14C uses a 27mm objective lens with an aperture number of f/1.2 and a Field of View (FOV) of 40°.
