Nivisys sets itself apart from other night vision device manufacturers through the use of ANV-110 Image Tube test equipment produced by Hoffman Engineering. This equipment is calibrated, NIST traceable, and correlated to the US Army Night Vision and Electronic Sensors Directorate (NVESD) at Ft. Belvoir, VA. This equipment gives us the ability to test critical image tube performance parameters to ensure complete conformance to customer specifications and compliance to all U.S. State Department regulations. At the assembled system level, we utilize the Hoffman ANV-126A and ANV-1026 test sets to validate that our systems meet all required specifications.
