Nitrogen Generating System

Nitrogen Generating System

Precision Optical has strategically invested in a nitrogen generating system (NGS), which effectively pumps 99.999% pure nitrogen throughout our entire facility.  We use nitrogen in key critical departments where cleanliness is of the upmost importance.  Our coating department is one of those critical areas.  Nitrogen is used for removing particulates and stubborn particles from optical surfaces prior to thin film deposition.  After optics are carefully loaded into their designated custom tooling, they are placed into staging areas where nitrogen is consistently bled into the environment to maintain cleanliness.
