1. Product Introduction
The PT Series, features a high-performance hybrid structure of PEEK polymer reinforced with titanium alloy, achieving exceptional durability and ultra-light strength.
The PT-40B represents the next generation of ultra-light night vision binoculars, designed for professional users who demand superior low-light performance, rugged field reliability, and unrestricted mobility.
Equipped with a premium PVS-14 optical system and fully compatible with Gen 3 autogated image intensifier tubes, the PT-40B delivers crystal-clear imagery, a wide 40° field of view ( 50°ultra-wide lens assembly will be
available Jan 2026), and excellent edge-to-edge resolution — all within a remarkably lightweight housing of under 470 g (without battery).
Its manual gain control, flip-up auto power-off, and automatic individual channel cut-off functions ensure tactical efficiency, enhanced safety, and tube protection under dynamic field conditions.
Engineered for special missions and extreme environments, the PT-40B is IP68-rated (20 m / 2 h submersion) to ensure uncompromised performance in maritime, desert, jungle, and mountainous operations.

3. Specific Function
1) Flip-up Auto Power-Off Function
It is suitable for installation on the helmet, automatically power-off after flip up(the NV will automatically turn off until the special Angle, and will not turn off when you look up vertically ), and power-off again when you flip down.
2) Automatic individual channel cut-off
which cuts power to the image intensifier tube, shutting it off when rotated beyond approximately 60 degrees from the center housing (well beyond realistic IPD adjustments), both to protect the image intensifier tube and prevent backsplash when the monocular pods are rotated away.
3) Manual Gain Control
After correctly installing MX11769 tube with gain adjustment function, turn the switch left and right to control the gain adjustment function.
