Image Intensifier Tubes are opto-electronic vacuum devices that amplify very low levels of light into visible levels for the human eye.
They exist of the following parts:
- Photocathode. Incoming light is converted into photo-electrons
- Amplifier. Here the electrons get accelerated
- Phosphor screen. Here the electrons produce a visible image
Image Intensifier Tubes are frequently used in modern night vision equipment.
In such Image Intensifier Tubes a micro channel plate (MCP) is used to accelerate the electrons.
The Image Intensifier Tubes of Photonis are build using the following scheme:
The following Image Intensifier Tubes are manufactured using the 18-mm production line of Photonis:
Disclaimer: Black spots are inherent to the production technology of nightvision tubes. In most tubes they are present. Black spots do not in any way affect the performance of the tubes.
