The most striking feature of the DTG-18N is the presence of four separate image intensifier tubes with four separate objective lenses arrayed in a panoramic orientation. The center two lenses point forward like traditional dual-tube goggles, giving the operator more depth perception, while two more tubes point slightly outward from the center to increase peripheral view. The two tubes on the right and the two on the left are spliced at the eyepieces. The operator sees the two center tubes somewhat overlapping the two outer tubes to produce an unprecedented 120° FOV. This is an absolute game-changer for the SOF community. The two right and two left tubes are housed in merged assemblies and are hung from a bridge, giving operators interpupillary adjustment options. They can also be easily removed and operated as independent handheld viewers. The IPD of the two system can be adjusted on the helmet mount.The DTG-18N is not only powered by a battery on the device, but also by a remote battery packs, tethered to the unit via a standard DC cable. It comes with a pack that accepts four 3-Volt CR123A batteries that tend to power the unit for 50-80 hours (IR off). The remote battery pack provides a secondary function as a counterweight, which is needed considering the goggle weighs about 880g..ModelDTG-18NStructural modehelmeted turnover four-eyedNVGBattery typeLithium battery (cr123Ax1) / cr123Ax4 external battery packPower supply2.6-4.2VInstallationHead mounted(standard American helmet interface)Control modeON/IR/AUTOOver power consumption<0.2WBattery capacity800-3200maHBattery life30-80HMagnification1X FOV(°)120x50 +/-2 °Horizontal 120+/-2 °Vertical 50 +/-2 °Parallelism of optical axis<0.1°IITgen2+ / gen 3GAInAutoLens systemF1.18 22.5mmMTF120LP/mm Optical distortion3% MaxRelative Illumination>75%CoatingMultilayer broadband coatingFocus range250mm-∞Focus modeManual focus facilityeye relief30mmPupil diameter8mmVisibility range-1(+0.5~-2.5)IPD adjust typeArbitrary continuously adjustableIPD adjust range50-85mmIPD lock typeManual lockIR850nm 20mWWorking temperature range-40--+55ºCHumidity range5%-95%WaterproofIP65/IP67Dimensions155x136x83mmWeight880G(without battery)
