The D-321 Generation 3ST Dual Tube Night Vision Goggles are a sturdy pair of binoculars with a lot of high quality offerings for both the amateur night vision enthusiast and the serious, tactically experienced, veteran of the field.
Thanks to the dual image intensifier tubes that the D-321 Generation 3ST night vision goggles offer, you won’t ever have to worry about interpupillary distance and frustrating, time consuming effort to focus your lenses properly. These dual tubes will provide you with the image redundancy that you need to effectively see targets in the dead of night, with a higher quality resolution and depth perception - qualities a monocular simply can never offer you.
The high quality and patented design behind the D-321 and its dual image intensifiers allows for a much more light weight and compact model than other night vision goggles, and you will truly feel this when you are carrying them or wearing them - as they can be head or helmet mounted, depending on your hands free needs.
These binocular goggles also come equipped with state of the art automatic brightness control which will keep these glasses calibrated to changing light - an absolute necessity for quick operations where you don’t have all night to sit around adjusting your binoculars. Automatic brightness control, or ABC, is just another of the many intuitive features that make these goggles so high in performance. These binoculars also come equipped with manual gain control for added functionality.
Technical specifications of this model include a Generation 3 image intensifier system, an amazing resolution of 57/72 lp/mm, a Field of View of 40 degrees, and a standard magnification of 1x. The lens system is 26mm f1.2. The Standard model has a non gated power supply.
The D-321 Generation 3ST ships with a flip up head mount, a hard case, a 3v CR123 Battery, and a standard operations manual.

Gen 3 Night Vision
Please note that most high end night vision devices are built per order. It may take 3-5 days or more for your order to ship. If timely shipping is important to you, please, contact us to verify availability prior to ordering.
By adding a sensitive chemical, gallium arsenide to the photocathode a brighter and sharper image has been achieved over 2nd generation units. An ion barrier film was also added to increase tube life. 3rd Gen. provides the user with good to excellent low light performance. 3rd Gen. Standard IIT Our standard 3rd generation image intensifier tubes are of the highest quality. They have a micro channel plate, GaAs photocathode, and a completely self-contained integral high-voltage power supply. These 3rd Generation tubes provide a combined increase in resolution, signal to noise and photosensitivity over tubes with a multi-alkali photocathode. Generation 3 is the standard for the USA military.
3rd Gen. Standard IIT Features:
• Photo Cathode type: Gallium Arsenide
• Resolution 64 lp/mm
• Signal-to-Noise Ratio 22 Typical
• 10,000-hour tube life
Delivery Time and Manufacturing Process for D-321G GEN 3ST DUAL-TUBE NIGHT VISION GOGGLE:
Most of our manufacturers do not keep products like D-321G GEN 3ST DUAL-TUBE NIGHT VISION GOGGLE assembled on the shelf. Night Vision tubes are kept separate from the body of the unit. When the order is placed, the manufacturer starts the order processing and assembly process which includes the following:
- Order processing - we collect all the necessary information including address and phone numbers. We also make sure that our customer ordered the correct product for their needs and that the product can be exported by US law to the country of destination. In some cases a signed export compliance form is required.
- QC - in this step the manufacturer will inspect all individual parts which will be used to assemble the night vision device for any defects.
- Production & Assembly - during production, all the parts are put together. Night Vision tubes in inserted into the body of the unit and all the complex electronics for the device are connected. This process takes place in a special lab called the "clean room" as even a small speckle of dust can cause undesired optical effect.
- QA - one the night vision device is assembled, it goes through a rigorous testing process to make sure it meets all the expected specifications and all parts function as expected. For this most manufacturers have a special "dark room" designed to allow testing of the units without causing incidental damage to the night vision tube by exposure to bright light.
- Packaging - this is a key process as well. In most case your night vision device will be shipped to you directly from the manufacturer but sometimes needs to be sent to us first. In either case items need to be packaged securely to avoid any kind of damage during transportation.
- Shipping - as described above items will most of the time ship from the manufacturer. For most domestic orders (unless shipping to POB or AFB) a premium shipper like FedEx or UPS will be used.
Only by following the above steps can we along with our manufacturers bring you - our customer - night vision products of highest quality, However as you can understand the above process can take several days to complete. For example if your device fails QA, the entire process restarts. Also at QC stage a manufacturer may realize that the tube they have in stock has a defect and a replacement tube needs to be ordered. Due to the complexity of this process, it is prudent to expect 3-4 business days for production and handling of the purchased device. Keep in mind that this process is designed to guarantee your satisfaction with the night vision device of your choice. It occasionally possible to expedite the process for urgent orders but addional fees or other restrictions may apply.
