The HVS-126A is a computerized system to evaluate NVG image quality. It will quite simply transform the evaluation process to give fast and accurate results time after time, which until now has been a subjective task for NVG 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 and a Pass/Fail is displayed for minimum resolution at high/low light settings and image quality defects.
