Why you can‘t compare conventional Night Vision Devices with our DNVG

A conventional night vision device is a monolith with consecutive optical path:

  • The objective lens system compiles the environmental light left over;
  • The photocathode tube amplifies the light and projects the image to the phosphorus screen which the user can see through the ocular.


Note: Operating life in this table are theoretical values only and will not be reached in daily operation!

1. Front Lens                        4. High Voltage Power Supply
2. Photocathode                   5. Phosphorus Screen
3. Microchannel plate            6. Eyepiece


The photocathode tube is the heart of conventional NVD.
The entire discussion on NVD generation only refers
to the tube technology:                                                                                        

GENERATION 1 (Developed in 1960's); Picture3.jpg                                         
Vacuum Tube Technology
Full Moon Operation
Amplification: 1,000
Operating Life: 2,000 Hours

GENERATION 2 (Developed in 1970's);                                         
First Microchannel Plate (MCP) Application
One-Quarter Moon Operation
Amplification: 20,000
Operating Life: 2,500 HoursGENERATION 2+ (1970s)
Development increased image tube bias voltage to improve gain.
Additionally, a glass faceplate was added to improve resolution.

GENERATION 3 (Developed in 1990's);Picture4.jpg                                          
Improved MCP & Photocathode
Starlight Operation
Amplification: 40,000
Operating Life: 10,000 Hour

GENERATION 3 Enhanced (2000's);
Improvements in the photocathode and MCP resulted in increased
gain and resolution.

... but without ion protective film. The filmless tube
provides ~20%                                                                            
better photoresponse, however more rapid degregation as well ...



doesn't work with any tube !!!

doesn't amplify light !!!

doesn't work with high voltage !!!

doesn't have a consecutive optical path !!!


What does that mean for the user ?

Our DNVG doesn't work with any tube ...

The photocathode tube is the most fault-prone AND the most expensive component of a conventional NVD. It suffers under bright light and doesn't work in daylight conditions or illuminated environments. If a light flash or a muzzle fire occurs, the sensitive phosphorus screen over-saturates or is shut-off by a high speed shutter.

Our DNVG doesn't amplify light ...

... it asses the image information. The amplification property of the tube boost everything: useful image information and noise as well. Our sensor feed the image information to a computer, where the image is analyzed and the useful information is enhanced and enriched and noise can be limited to a minimum.

Our DNVG doesn't work with high voltage ...

... and therefore doesn't need special measures to ensure Electro-Magnetic Compatibility (EMC) or precautions at high humidity.

most important however ...


Our DNVG doesn't have a consecutive optical path !!!

Conventional NVD's require that all their components - optically seen - are in one line; from the objective through the tube to the ocular. This singular line makes these devices bulky. Picture5.jpg
Of course, the implementation of prisms allow alternative product designs, but also increases the weight of the gear.

And - any e.g. LASER flashes will be directly conveyed to the users eye (after having violated or destroyed the tube).




How does the system work?

The Goggle comprises TWO independent systems:

  • Night Vision Camera System

 high quality lens system compiles what is left of the light and focuses the night image to an extremely sensitive semi conductor chip (CCD). From here the digital image is fed to the "Power Box" where the sensor can operate under every light condition. Only intense laser light might degrade the sensor, but not the human eye (!) as the OPTICAL PATH ends here.


The sensor captures visible light and Infra Red up to 1.100 nm, which allows you to recognize heat information (not comparable with a thermal cam).

  • A General Purpose Display
    ... which will be discussed later


"Power Box", the Image Data Management SystemPicture11.jpg

The "Power Box" - Real Time Computer System for image data management of:

  • the digital data stream captured by the Goggle objective system
  • further image source, e.g. external observation cam, thermal cam,
    GPS or communication systems
  • data input / output management, e.g. video output, connection
    to a radio receiver / sender, etc.
  • Powerful battery pack also supplies external equipment
    (IR-Illuminators, external cams, etc.)


The Goggle comprises TWO independent systems:

  • Night Vision Camera System
    ... we already discussed earlier
  • A General Purpose Display

two separate screens with separate oculars provide Pseudo-3D View

 - to view the enhanced Night Vision Image provided by the "Power Box"
 - to view images from other image sources
 - to show text messages
 - to overlay moving maps (* future option)‏

* future options are available soon as SW-Upgrade. The Goggle and the Power Box doesn't need to be sent to the factory!

Digital Night Vision Goggle - Interfaces

  • LEMO Plug (FGA.1B.316.CLAD52ZG, 16 pin)‏Picture12.jpg
  • Extremely robust
  • Mechanical Coding to ensure correct plug in
  • Digital Input for Onscreen Display Messages
  • Analog Input / Output for ANY (!) Image Source
  • Digital Input / Output for Control Functions
  • 5 V / 12 V supply for external gears,
     - e.g illuminators
     - or external cams



Using the DNVG

  • The DNVG can be used
     - passively, i.e. without using IR-Illumination or
     - actively, i.e. with using IR-Illumination
  • Carefully adjust the Illumination Control Knob at the Power Box:
     - Most probably the LIGHT INTENSITY Switch (6) at the Goggle should be switched OFF when working with   

     - A high level of IR-Illumination may cause reflections

     - Carefully use the IR-Illumination when looking through a window or when wearing the Goggle underneath a 
       visor; most probably it will cause bad reflections. Use external IR-Illuminators instead.
       When wearing the Goggle underneath a visor, make sure that the visor is properly cleaned and as close as    
       possible to the goggle. The objective here is to look straight through the visor.

     - The built-in illuminator is designed for in-house operations. For far distance vision use an IR flashlight.

     - In a forced entry operation consider only one person having the IR-Illumination switched on. Multiple users  
       with IR-Illumination switched on may glare each other out when looking at each other (same when looking in 
       a mirror).

NOTE: With any type of IR-Illumination you are visible for other people working with IR detecting devices.

Comparison AD2V DNVG and Conventional NVD:

  • Unique System Concept: Night & Day Vision, Protection, Text Messaging, Video Interfacing
  • Rapid head movements possible
  • Designed for combat / forced entry operations
  • Full protection for eyes + part of the face
  • Goggle fits under a combat helmet + visior (can operate through visor)
  • No light emitted by the goggle, so the user remains in the dark at night
  • High Tech Sensor Chip (CCD) allowing image enrichment and field weighting
  • High resolution, 63 up to 70 lp/mm through high quality objective/sensor systems; "pixel view" through digital micro screen (Note: the screens have a quarter of the camera resolution)
  • CCD sensor can operate at night & day 
  • Automatic Gain Control to adapt the CCD sensor sensibility to the incoming light; field weighting & enhancement; Night & Day View  
  • High Contrast Black& White picture
  • Significantly reduced blooming and over-saturation effects
  • Small transition range between good view and "snow" (passive mode, i.e. without IR) at the sensor limit (0,000029 lux)
  • No latency (smeared pictures) due to digital sensor technology and real time computing (24 images / s) 
  • If you move your head very quickly the picture may "jump" as 24 images are not enough to provide a "jump-free" impression
  • Image capturing and image presentation separated, i.e. camera and video screen are separated components
  • Weight / size: the DNVG is about a 3rd of the weight of a conventional NVG
  • In order to keep the low weight and small size the DNVG is limited in the size of the objective lens system
  • 1:1 objective is ideal for operation ranges of 100 m; depending on the test scenario you can see 200 m and more
  • 2:1 objective lens can be used for distances up to 400 m (and more)
  • External Cams connected to the DNVG can reach nearly every distance range
  • Due to the separation of image capturing and image presentation 
  • the image can be exported to the interface
  • images from other source can be displayed at the goggle screens

Frequently Asked Questions:

Q: Is the Digital Night Vision Goggle a Passive or an Active System?
A: Both! - Due to its extremely sensitive sensor the Digital Night Vision Goggle can be used as a passive system. With
    the integrated IR-Illumination the goggle becomes an active system for use in very low light or total darkness.

Q: Can the Digital Night Vision Goggle be used in foggy environments?
A: The goggle sensor receives more or less regular light extended to the IR spectrum, i.e. fog will reduce the contrast
    but not more than other night vision technologies.

Q: Is it possible to aim a weapon when wearing the Digital Night Vision Goggle?
A: The DNVG is basically designed for forced entry situations where typically short weapons are used. Tests have 
    proven that the DNVG supports operating with short weapons especially when combined with laser or IR pointers.
    Take care that the pointer intensity e.g. with AIMPOINT is reduced, keeping the environmental vision in the same
    level than the pointer intensity. Older aiming systems like HENSOLD which are not adjustable are not recommended.
    Best results can be achieved with IR laser pointers such as GLOCK Tactical Light also illuminating the targeted
    environment. When using long weapons the laser pointer must be used. As an alternative the camera image
    captured by camera systems mounted on the weapon can be fed into the DNVG.

Q: The Digital Night Vision Goggle has one objective lens system only. What is meant by "Pseudo-3D Vision"?
A: The camera module works with a fixed focus and wide range in depth of focus. In comparison with a human eye
    permanently focusing on the object, the natural depth perception is restricted either with one or two objectives. The

Q: Is there a lag time in the image?
A: No! The Digital Night Vision Goggle is a real time system; however under absolute darkness and low illumination the
    video signal may appear blurry with rapid head movements.

Q: Is the Digital Night Vision Goggle a 3rd Generation Product?
A: This new technology cannot be compared with any CRT-based night vision generations, however it provides
    significant functional advantages in comparison to all CRT-based products!

Q: What is the purpose of the Optional Socket?
A: The Digital Night Vision Goggle not only provides leading edge night vision technology; it is also an investment for
    the future. The Option Socket is designed to interface with other devices.

Q: Can the field of vision be extended?
A: Yes, we offer another objective lens system. The standard configuration however is designed for forced entry
    operations; therefore the DNVG must provide the same filed of vision as provided by the human
