There are two technologies available for night time, low light and adverse weather conditions observation: Image Intensification and Infrared Thermal Imaging. Both have their own advantages as well as limitations. The special purpose of DSQ-20M system is to combine both technologies. It allows fully and effectively exploit their capabilities by creating “Hybrid” or so-called “Fusion” Enhanced Night Vision observation system. DSQ-20M is lightweight, portable, individual optical electronic hand held or helmet mountable device combines near infrared (NIR) Image Intensifier Tube, Long Wave infrared (LWIR) Thermal Imaging Engine and Infrared laser aimer/marker.  DSQ-20M very effectively exploit multi-technology capabilities by creating unique Fusion Enhanced Night Vision observation system. Whatever is missing under Image Intensified Night Vision device observation, will be detected by Thermal Imaging Channel. And whatever is missing under Thermal Imaging observation, will be detected by Image Intensified Night Vision Channel. Both channels dichoptically fused. Built in Infrared Laser has dual functions: 1. Aimer/Pointer, i.e. IR Marker, 2. IR Illuminator which allows to use Night Vision Channel in total darkness. DSQ-20M Enhanced Night Vision System guarantees 100% night time, low light and adverse weather detection capabilities. DSQ-20M is The most desired by World's Law Enforcement and Military Users!
