PVS7 Series Night Vision Goggles.

soldier wearing a pvs7 goggleThe ATN PVS7 Night Vision Goggles are night goggles but they also function at dusk and dawn with the light filtering lens caps on.

These are head and helmet mounted goggles built to military specifications for the military. These are standard issue to U.S. Army ground troops.

  • Hand-held, head-mounted or helmet-mounted. The head mount assembly with 3 brow pads is included. Helmet mounts are optional.
  • Built in IR illuminator. The left eye piece display has an illuminator on indicator.
  • Bright source protection shuts the device off if the light levels are too high. The on / off button will turn the device back on.
  • Bright source protection shuts the device off if the light levels are too high. The on / off button will turn the device back on.
  • Automatic brightness control adjusts the brightness of the screen automatically.
  • Adjustable interpupillary distance which allows you to position each display in front of each eye.
  • Right and left ocular ( eye ) lens focal adjustments which allow you to focus the right display for your right eye and the left display for your left eye.
  • A front lens focal adjustment which allows you to focus the device on objects at distances from 1/4 meter to infinity.
  • 2 removable ocular lens demist shields to help prevent condensation from forming on the ocular lenses during rapid temperature changes and heavy and long use.
  • 1 removable objective ( front ) lens sacrificial cover to protect the objective lens from damage caused by blowing sand.
  • Front lens cap.
  • Shoulder strap.
  • Lens tissue.
  • Neck cord.
  • Soft carrying case.
  • Manual.

The PVS7 series of goggles are built with either 2nd generation or 3rd generation tubes.

For additional information you can download and read the ATN PVS7 User Guide.

If you want to mount a PVS7 on your MICH (Modular Integrated Communications Helmet) helmet then you will want the PVS7 MICH mount.

If you want to mount a PVS7 on your PASGT (Personal Armor System Ground Troop) helmet then you will want the PVS7 PASGT mount.

Night vision and light levels.

  • Night vision requires some light (moonlight, starlight, etc.) to operate. The level of equipment performance depends upon the level of light.
  • Starlight and moonlight are reduced by clouds.
  • Starlight and moonlight are also reduced by trees and buildings and anything else which creates shadows. Night vision is less effective when viewing into shadows and other darkened areas.
  • Night vision is less effective when viewing through the rain, fog, sleet, snow or smoke. Night vision will not “see” through dense smoke.
  • With night vision you only see shades of green or shades of grey depending on the type of display.
  • As with any night vision device, you are always looking for contrasts and movement.

Night vision generations.

  • 2
    • 40 - 45 lines per millimeter resolution.
    • 5,000 hours average tube life.
    • Signal to noise ratio 12 - 10.
  • WPT ( White Phosphor Technology © )
    • Typically 60 - 74 lines per millimeter resolution.
    • Signal to noise ratio 18 - 26.
    • 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. ATN's 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.
    • 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.
    • 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.
  • 3
    • 64 lines per millimeter resolution.
    • 10,000 hours average tube life.
    • Signal to noise ratio 22.
    • 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.
    • ATN's 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.
  • 3P
    • 64 - 72 lines per millimeter resolution.
    • 10,000 hours average tube life.
    • Signal to noise ratio 26.
    • ATN Night Vision units with the 3P designation use ITT Pinnacle™ Image Intensifier tubes. The industry leading ITT Pinnacle™ image tubes utilize a gated power supply providing truly outstanding performance in high-light or light-polluted areas, such as urban environments. The Pinnacle™ tube with gated power supply minimizes any “halo” effects. “Halo” is often associated with using night vision devices in an urban area where random street lights are often an issue with early Generation Night Vision devices. Night Vision units with Pinnacle™ tubes have a resolution of 64-72 lp/mm and a typical signal to noise ratio of 26. All Night Vision devices utilizing Pinnacle™ Image Intensifier tubes come with ITT data record sheet. Units with Pinnacle™ tubes are not available for export.
  • 4
    • 64 - 72 lines per millimeter resolution.
    • 10,000 hours average tube life.
    • Signal to noise ratio 25 - 30.
    • 4TH GENERATION GATED/FILMLESS TECHNOLOGY represents the biggest technological breakthrough in image intensification of the past 10 years. By removing the ion barrier film and “Gating” the system Gen 4 demonstrates substantial increases in target detection range and resolution, particularly at extremely low light levels.
      • The use of film less technology and auto-gated power supply in 4th generation image intensifiers result in:
        • Up to 100% improvement in photo response,
        • Superb performance in extremely low light level (better S/N and EBI),
        • At least triple high light level resolution (a minimum of 36 lp/mm compared to 12 lp/mm).
      • ATN's Autogated / Filmless inverting image intensifier tubes improve night operational effectiveness for users of night vision goggles and other night vision devices. The filmless micro channel plate provides a higher signal-tonoise ratio than standard 3rd Gen. IITs, resulting in better image quality under low-light conditions. An Autogated power supply further improves image resolution under high light conditions and a reduced halo effect that minimizes interference from bright light sources. The reduced Halo maximizes the effectiveness of the Night Vision device in dynamic lighting conditions such as those experienced, for example, in night operations in urban areas.
    • With significant improvement in contrast level and in performance under all light conditions, 4th generation represents the top of the line performance in the night vision market.
