Understanding Visible technology

Visible technology encompasses a wide range of devices and systems designed to work within the visible spectrum of light. This spectrum covers wavelengths between approximately 380 to 780 nm, representing the colors that the human eye can perceive. In this visible technology, Photonis has successfully set a benchmark for the image intensifier tubes. In addition, Photonis has developed and promoted low light and intensified cameras with high performances. 

Photonis' cutting-edge image intensifier tubes for Night Vision

Photonis proudly leads the industry in crafting cutting-edge image intensifier tubes for military, space, and commercial applications, advancing night vision capabilities.

Vacuum tube-based Image Intensifier tubes  consist of several essential components; a Photocathode, a Microchannel Plate (MCP) and an anode. These components work together to amplify input signal, creating a rich and dynamic output.

Principles of Operation

Principles of Operation

In the first step, existing ambient light passes through a photocathode, which converts the incoming photon signal into a photo-electron.

In the second step, photoelectrons are drawn by an electrical field into the MCP where they impinge multiple times on the inner walls and thereby multiply several thousands of times. In photon counting applications the multiplied electron signal is detected using an anode. In the instance of photon imaging applications, the anode converts the electron back into photons to produce an image.

What is an Image Intensifier Tube and how does it work?

An Image Intensifier Tube (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.

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.
