HGH Infrared Systems provides a compact and portable test bench to perform maintenance on NVGs, measure their quality over time, or compare the performance of similar model NVGs. Good compacity and ruggedness allow the customer to transport and use the bench in the field, avoiding the shipment back of NVGs for testing and maintenance activities. Tests are easy to use thanks to video-assisted, and a very high-resolution camera replaces the human eye during testing to prevent subjectivity.

Another HGH test system allows a quick adjustment of NVG in repeatable night conditions (quarter moon or starlight) and executes a Go/ No Go visual test just before mission.
