Night vision tubes

Be the first to see and get strategic advantage

Within Exosens Group, Photonis is the world leader in the design and manufacturing of state-of-the-art image intensifier tubes for military, space, and commercial applications. Image intensifiers are devices that intensify or amplify low light level images from natural sources, such as starlight or moonlight, or from artificial sources such as street lights or infrared illuminators. The light passes through several internal components to multiply the existing light several thousand times, producing a much brighter image that can be seen by the human eye.

Over the years Night Vision has become a key opto-electronic technology in modern warfare as more and more operations take place by night. Photonis offers a variety of different options so that users can find an image intensifier tube that will work for their specific mission or operational requirement.

Night Vision enables to operate safely in night and low light conditions. Only quality image intensifier tubes can provide the best night vision images. That’s why it is important, not only to choose a good quality night vision goggle, but to equip it with the best possible image intensifier tube. In modern warfare, individual operations under the cover of darkness underscore the tactical and operational importance of superior night vision capabilities. As a result, a Night Vision Device (NVD) is no longer being seen as a luxury item, but as essential gear which every combat soldier in the field must have. As greater numbers of NVDs are being placed in service, their performance, reliability and ruggedness have significantly improved. Easy to deploy and inexpensive to maintain, NVDs have become crucial in maximizing a soldier’s operational capabilities in combat.

Frequently asked questions

What is Night Vision?

Night vision enables to operate safely in night and low light conditions. Owning the best night vision equipment alone will not provide the best images. That's why it is important to opt for a high-quality image intensifier tube (IIT) to have the best possible performance.


Over the years, night vision has become a key opto-electric technology in modern warfare as more and more operations take place by night. Photonis offers a wide range of intensifier tubes, enabling users to find the one that will work for their specific mission or operational requirement.
 

What is an Image Intensifier Tube (IIT)?

An IIT is a module that intensifies, or amplifies, low light level images into levels that can be seen by the human eye. The IIT collects the existing ambient light from natural sources, such as starlight or moonlight, or from artificial sources such as street lights or infrared illuminators. The light passes through several internal components to be multiplied several thousand times, producing a much brighter image that can be seen by the soldier through the night vision device.
 

How does an image intensifier work?

First of all, photons (light) are converted into electrons by the photocathode. Then, they are accelerated through an electrical field and hit the microchannel plate walls to generate secondary electrons that in turn will generate more electrons into what is called an « electron avalanche ». Then, multiplied secondary electrons are accelerated through an electrical field, hit the phosphor screen layer and are converted back into light. Finally, the image is projected through the eye-piece of the night vision device.
 

What is the difference between night vision and infrared products?

Night vision is the ability to operate safely in night or in any environment under low light conditions. Whereas, infrared imaging products, such as thermal (LWIR) or Shortwave Infrared (SWIR) sensors, are optimized for day-through-night lighting conditions and support surveillance & security applications, industry & research projects, and mobile use.  

 

What are the different light levels?

In night vision, we have defined 5 different light levels from 1 (full moon) to level 5 (overcast starlight) The better the image intensifier tube, the better the image quality in low light conditions.
