Distortion Free New Material Four Eyes Panoramic Night Vision

Model: DTG-18

Short Description:

Product Description:

With the new technology, Detyl developed a new Ground Panoramic Night Vision Goggles which called DTG-18N, The purpose of the DTG-18N is to provide the operator more information under goggles, allowing him to more quickly move through the OODA Loop (Observe, Orient, Decide, Act). 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..

DTG-18 available for state military and law enforcement.

With the new technology, Detyl Optics developed a new Ground Panoramic Night Vision Goggles

which called DTG-18 GPNVG, The purpose of the GPNVG is to provide the operator more

information under goggles, allowing him to more quickly move through the OODA Loop (Observe, Orient, Decide, Act).

The most striking feature of the GPNVG 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.

1. Battery installation

As image 1, put a CR123A battery in the house by correct direction, clockwise rotate the cover and tighten.

2. Turn on

As image 2, clockwise rotate power switch, make it at ON position, the device turn on and system working. 3 different working mode for you to choose. At "ON" only tube working, at "IR", tube and IR both working, at "AUTO" the IR will auto turn on or shut off according to outside light level.

3. IPD adjusting

It design with IPD adjusting knob at the side of the bridge, user can rotate the knob for adjusting, as image 3.

First, let the left eye aim at left eyepiece, look through be a circle view, same as right eye, close the left eye and see if the right eye can see the image clearly, back to left eye and adjust the IPD accordingly. it can fit different users.

4. Diopter adjusting

Choose a suitable light level target, do not remove the objective cover, adjust the diopter as image 4, turn the knob clockwise and counterclockwise to fit eyes, diopter adjusting stop when view the clearest target image. Both left and right use the same way.

5. Focus adjusting

Focus adjusting at the objective lens, please adjust the eyepiece before adjust objective. Please choose dark light level and open the cover, as image 5, aim at target, turn the objective ring clockwise and counterclockwise, till you see the clearest image, focus adjusting finished. The focus should adjust again when you view the different distance target.

6. Wording Mode

The switch has 4 position (OFF, ON, IR, AT(Auto)), and 3 working mode(except OFF), showed as above image 2;

OFF: Device shut off and not working;

ON: Device turn on and working, the IR does not working;

IR: Both device and IR are working;

AT(Auto): IR auto shut off or turn on according to light level around;

7.IR mode

When the light level low(fully dark), the device could not see clear image, rotate the knob to IR position, the build-in IR light will turn on, the device can be used again. Note: You are easy to be found when IR working;

8. Auto Mode

It is different with IR mode, AUTO mode start the light level sensor, it transfer the level value to the controlling system, the IR will turn on when the light level is low or fully dark, the IR will auto shut off when light level is higher enough. The whole system will auto shut off when the light level above 40Lux, the tubes will be protected.

FAQ:

1. Tube not working

A. Please check if battery in right direction; B, check if the battery has enough power; C: confirm if the light level is too high(almost like night level);

2.View image not clear

A: Check if eyepiece and objective lens dirty; b: If the objective lens cover opening at night condition, please do not open it at day light; c: Check if the diopter adjust to the right position; d: Check if focusing to right position; e: If turn on the IR at fully dark condition;

3. Auto testing not work

When the auto shut off function does not work at high light level, please check if the sensor is cover;

Notice:

1. Anti glare

The device design with auto anti-glare function, it will shut off at high light condition. Even though, repeated strong light exposure will also accumulate damage, so please do not put it in strong light environment for a long time or many times, so as to avoid permanent damage to the device.

2.Moisture-proof

This NVD design with waterproof inner structure, normal IP65 waterproof, the IP67 optional, well long term humid environment will also slowly cause damage to the device, so please store the it in dry environment.

3. Using and storage

It is high precision photoelectric products, please operate it according to this user manual, please take the battery out if do not use it for long time. Please keep it in a dry, ventilated and cool environment, and pay attention to shading, dustproof and impact proof.

4.Please do not open and fix it by yourself when the device is damaged during normal using or improper using, please contact our dealers for after sales service.
