Combat Ability 24/7

The sniper teams have to operate regardless of light and weather conditions. Night vision devices provide enormous benefits. They enable personnel to carry out operations under conditions that would not otherwise be possible. However, these benefits carry considerable risks. For instance, individuals often become over confident about their ability to use image intensification and infrared devices. In consequence, the use of night vision equipment is an increasingly common factor in military incidents and accidents. Fire ‘Blue’ against ‘Blue’ or innocent civilians is intolerable, even at night.

Clear identification of the enemy has become vital. Armies have invested heavily to procure ever better night-vision systems and improved training for night combat. Night vision capability enables soldiers to see their surroundings in low or no light conditions, but that’s not good enough. Soldiers must have night combat capability which enables them to take aim and to operate their weapons or weapon system effectively in no light conditions.

This article describes different night vision technology and some night vision goggles.

Different Systems

Light Intensifier (I²): There is usually always a little bit of light, even from the moon or stars, so these systems intensify the little light that there is to give an image. However, they will not function inside a dark room, for example, and will require the use of IR beamers. Photons in the near-infrared spectrum (approx. 750 to 950nm), which is invisible to the human eye, are collected and collimated in the objective lens and converted by a photocathode into electrons. A micro-channel plate then amplifies these electrons by a zillion-fold and transforms them into visible light appearing on a phosphor …read more
