The Night Vision Test Set, TS-4348/UV, provides a standard by which field personnel may determine the resolution performance of night vision devices.Such field assessment is essential to assure mission success and personnel safety. The test set contains a standard resolution target “chart”, uniformly illuminated with near infrared light optimized for evaluating performance of Gen 2 and Gen 3 devices. The system can be used to test goggles, weapon sights and drivers’ viewers. Two toggle switches enable the operator to select high and low light level test conditions for both Gen 2 and Gen 3 systems.
