In ATNs continuing effort to supply our clients with cutting edge Night Vision solutions we are proud to introduce a new line of select units based on ATN White Phosphor Technology© (WPT™). Studies show that nighttime scenes appear remarkably more natural in black and white versus the usual green. B&W provides clearer information about contrast, shapes and shadows. ATNs White Phosphor Technology© provides users with this natural B&W night vision image. Operators that tested units that use ATN WPT™ reported a significantly better degree of detail, overall contrast, full moon similarity and range of shades. WPT™ provides more discriminating shades of intensity between white and black than between green and black resulting in better contrast and depth perception then when compared to green phosphor NVG’s. The majority of the WPT™ performance characteristics are on par or better then the latest Gallium Arsenide based image intensifier tubes. WPT™ specifications include typical resolution of 68lp/mm (with some over 74lp/mm) and Signal-to-Noise figures as high as 25. 7 out of 10 users name WPT™ as a “Night Vision Preference” when compared with common green night vision, especially in an urban environment. “No lab testing needed on WPT™ – the depth perception is phenomenal and noticeably better than what I used in the past.” – SOF Operator K. WPT™ is available now in limited quantities in a wide variety of systems such as ATN PVS14/6015 tactical monocular, ATN NVM-14 multifunctional pocket-scope/goggle, ATN Marsx4 and ATN Marsx6 medium to long range weapon sights and on the FIITS-14 where WPT™ is optically fused with thermal imaging. Designed for Special Ops WPT™ is not a toy. If your life depends on your gear and you want to improve your operational effectiveness you should check it out.

Delivery Time and Manufacturing Process for ATN PS28-WPT Night Vision Clipon Sight:

Most of our manufacturers do not keep products like ATN PS28-WPT Night Vision Clipon Sight 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.

Questions on ATN PS28-WPT Night Vision Clipon Sight

From on

Q: I am considering the ATN PS28-WPT to mount in front of a Viper Hog Hunter scope. The VHH has a 56mm adjustable objective lens and will sit on a SA .308.. This seems like a good scope for this application. Is there an adapter that attaches from the NV device to the day scope?

A: Hi John. PS28-WPT night vision clipon will do very well on that scope. Depending on your setup, you may need an adapter for the scope. The clipon includes everything you need if you will be mounting on a rail in front of your scope. However, if you do not have a rail or don't have enough room on the rail and need to mount directly onto your scope, then you will need the additional adapter part number ACDNPS28SM01.
