De-fog and Waterproof your Optics with Nitrogen

Nitrogen gas is often used with optical instruments such as night vision goggles, telescopes, microscopes, binoculars, and cameras for a number of reasons.
  1. Purging - Night vision goggles and other infrared and thermal imaging devices require purging with N2 gas in order to eliminate air from the goggles that could affect the clarity of vision that is so vital to these instruments.  
  2. Prevent Internal Fogging - Filling optical instruments with Nitrogen replaces naturally occurring Oxygen and prevents the presence of moisture that can fog the devices.
  3. Create a Waterproof Environment - Some optical instruments purged with Nitrogen are then sealed to prevent any loss of N2 gas caused by changes in pressure or temperature.  This sealing process makes Nitrogen-purged instruments waterproof.
  4. Prevent Fungus and Mold Development - Nitrogen is a dry gas able to absorb and eliminate moisture when used to displace Oxygen in an environment.  The presence of Nitrogen prevents the development of fungus and mold that can easily form in moist, enclosed atmospheres.
Routine Nitrogen Purging of Optical Instruments

Nitrogen is such an important element in the efficacy of optical instruments.  Some devices require routine Nitrogen purging to ensure optimal results - that the instruments remain fog-proof and waterproof.

For instance, military personnel regularly purge night vision goggles to refill them with dry Nitrogen gas and eliminate them of contaminants and moisture.  For this purpose, a compact, portable Nitrogen Generator provides the best possible solution for purging.  Especially for soldiers in the field, a Nitrogen source that is lightweight, portable, reliable, safe, and efficient is the best possible choice.

South-Tek Systems manufactures portable Nitrogen Generators used exactly for this purpose.  In fact, the N2 GEN portable system has recently completed the military EMIP review and is proven to enhance safety, survivability, reliability/maintainability/sustainability (RMS), distribution/mission enhancements (DME), and mobility for warfighters.
