Optical instruments rely on nitrogen for a process known as “purging”, called optics purge. This process ensures that the optical lenses remain fog-proof or water-proof. Purging with N2 gas can apply to a variety of optical instruments, including night vision goggles, binoculars, cameras, microscopes, telescopes and more.
Many of the products that rely on nitrogen gas for optics purge are used by the U.S. military. Soldiers in the field rely on a variety of optical equipment for a number of operations. For example, soldiers regularly rely on night vision goggles to guard bases, plan maneuvers and scout out the enemy. In order to keep their goggles from fogging, soldiers must regularly purge them with nitrogen to eliminate contaminants and moisture. Compact, portable Nitrogen Generators are designed specifically for this purpose. These generators provide a lightweight, safe and reliable solution to optics purging in the field.
Using nitrogen doesn’t just prevent the optical equipment’s lenses from fogging on the outside. The benefits of using nitrogen to purge optical equipment also include preventing internal fogging, creating a waterproof environment, and preventing the formation of mold and mildew. Filling optical equipment with nitrogen replaces the naturally occurring oxygen and prevents the accumulation of moisture, which can not only fog the equipment, but can also lead to the development of mold or fungus.
After the equipment is purged with nitrogen, it can then be sealed to further prevent any accumulation of moisture. The sealing process makes nitrogen-purged equipment waterproof, preventing moisture from entering the area around the lenses and putting a proactive halt to the growth of microorganisms that thrive in moist environments. Mold, fungus and mildew develop most rapidly in warm, moist enclosed spaces. Using nitrogen to purge and then seal optical equipment is the most effective solution to preventing these unwanted effects. And the most cost-effective, reliable way to purge optical equipment could be with a portable Nitrogen Generator from South-Tek Systems. Whether being used in military operations, field research, or mass-production factories and laboratories, South-Tek Systems can deliver an on-site Nitrogen Generation System that provides you with a never-ending supply of high-purity N2 for safe, effective use.
