The AN/PSQ-20B is a helmet mounted dual sensor (night vision AND thermal) monocular.
By incorporating the latest in technology developments, the L-3 AN/PSQ-20B (ENVG) provides the operator with significantly improved targeting and identification in all battlefield conditions and light levels. The AN/PSQ-20B (ENVG) uses image intensification technology fused with thermal imagery, thereby bridging the gap in performance and capability for both of these sensors. The AN/PSQ-20B (ENVG) is based upon the combat proven Insight Fusion Goggle System (FGS), and is compatible with aiming lasers operating in the near infrared wavelengths.
