    HVS-126A Hoffman Vision System

    The HVS-126A is a computerized system to evaluate night vision monocular and binocular systems for image resolution and quality. It will quite simply transform the evaluation process to give fast and accurate results time after time, which until now has been a slow and laborious task for NVD maintenance personnel. 

    The HVS-126A uses a high resolution video camera to capture live images generated by the Hoffman ANV-126A test set through a NVG. The images are analyzed by the proprietary software running on a Microsoft Surface Pro Tablet.

    There is no requirement for the maintenance personnel to be dark adapted. The process may be carried out under normal lighting conditions. Test results are automatically calculated, displayed for Resolution at both high and low light settings, and Spot Defects (Blemishes). This is all achieved in a fraction of the time it would take to carry out this task manually, giving fast, accurate, consistent results. The HVS-126A significantly improves productivity and most of all, night vision user safety.
