Professional Image Tube Testing

Nivisys Industries 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 Labs at Ft. Belvoir, VA.  This equipment gives Nivisys the unique ability to calculate Image Tube FOM (Figure of Merit) as required by the US State Department for Image Tube exports.
