Optical instruments rely on nitrogen for a process known as “purging, ” referred to as optics purge. This process ensures that optical lenses remain fog-proof and water-proof. Purging with N2 gas can be applied to a variety of optical instruments, including night vision goggles, binoculars, cameras, microscopes, telescopes, and more.
Many products that rely on nitrogen gas for optics purging are used by the U.S. military. Soldiers in the field depend on various optical equipment for many operations. For example, they regularly use night vision goggles to guard bases, plan maneuvers, and scout the enemy. To prevent their goggles from fogging, soldiers must frequently purge them with nitrogen to eliminate contaminants and moisture. Compact, portable nitrogen generators are specifically designed for this purpose. These generators provide a lightweight, safe, and reliable solution for optics purging in the field.
Using nitrogen doesn’t just prevent the lenses of optical equipment from fogging on the outside. The benefits of using nitrogen to purge optical equipment include preventing internal fogging, creating a waterproof environment, and inhibiting the formation of mold and mildew. Filling optical equipment with nitrogen replaces the naturally occurring oxygen, preventing the accumulation of moisture that can not only fog the equipment but also lead to the development of mold or fungus.
After purging the equipment with nitrogen, it can then be sealed to prevent any further accumulation of moisture. The sealing process renders nitrogen-purged equipment waterproof, keeping moisture from entering the area around the lenses and proactively halting the growth of microorganisms that thrive in moist environments. Mold, fungus, and mildew develop most rapidly in warm, humid enclosed spaces. Using nitrogen to purge and then seal optical equipment is the most effective solution for preventing these unwanted effects. Additionally, a portable Nitrogen Generator from South-Tek Systems represents the most cost-effective, reliable method to purge optical equipment. Whether used in military operations, field research, or mass production in factories and laboratories, South-Tek Systems can deliver an on-site Nitrogen Generation System that provides a continuous supply of high-purity N2 for safe, effective use.
South-Tek System’s portable nitrogen generator provides easy and quick optical purging for various industrial, military, or consumer applications.
