XD-4 Image Intensifier Tube

The XD-4™ technology sets the European standard for low-light-level imaging. XD-4™ Image Intensifiers perform extremely well in all environmental conditions.

Proven quality performance
Small halo
Broad spectral sensitivity
Improved SNR, MTF and Resolution
Available with an Auto-Gating power supply unit


Image intensifier tubes intensify or amplify low light level images into levels that can be seen by the human eye. The XD-4 Image Intensifier tube features a broad spectral sensitivity range which results in a clear and high-resolution nighttime picture. An introduction of new and innovative production technology used in the manufacturing process of the XD-4 resulted in improved performance of the Signal-to-Noise Ratio (SNR), the Modulation Transfer Function (MTF) and resolution of the tube. When you compare the improvements of the XD-4 in these areas and add in the smaller halo size and extended lifetime you will quickly be convinced of the unique performance specifications this tube offers. The XD-4 is also available with an Auto-Gated power supply.


  Minimum Typical Maximum Unit
Figure of Merit (FOM) 1200 1400    
Signal to Noise Ratio (SNR) 20 22    
Limiting Resolution (at center) 60 64    
High Light Level Resolution (200lx) 50     lp/mm
Weight (ANVIS)   70 75 g


Many of Photonis' image intensifier tubes are available in different sizes and with different phosphor solutions. Our specialists are standing by to discuss your needs and help you find the perfect solution.

Phosphor Solutions

Phosphor Solutions

White Phosphor

White Phosphor Scene

The latest technological achievement providing the greatest clarity of image when operating in urban, desert or forested environments. For these applications, the night vision user should turn to a white phosphor tube. Studies have shown that night-time scenes appear remarkably more natural in black and white versus the usual green. White phosphor also provides much clearer information about the contrast, shapes and shadows within an environment. 

Main Benefits: 

  • Greater image clarity
  • Scenes appear more natural
  • Clearer information regarding contrast, shapes, shadows
  • Perfect for urban, desert or forested environments

Green Phosphor

Green Phosphor

The industry standard for more than 40 years, green phosphor is the perfect choice for operators that complete missions in the jungle or deep dark areas of the world. The enhanced contrast and depth required for operating in these densely packed environments are ideally suited to the green phosphor coating. The higher gains and stronger contrasts of the green phosphor enable the clarity of the image required for those operating without the advantage of ambient light sources to enhance the image. 

Main Benefits: 

  • Enhanced contrast and depth
  • Higher gain and contrast provide better clarity
  • Perfect for jungle or deep dark environments

Innovative 16mm Size

Innovative 16mm Size

Photonis’ 16mm image intensifier tubes have been designed to meet the SWaP requirements of the modern night vision user. Utilized by our very own PD-PRO-16B and PD-PRO-16M devices, these powerful 16mm image intensifier tubes offer a reduced size, weight and minimum power consumption without sacrificing performance. The weight of a 16mm image intensifier tube has been reduced by 30 grams in comparison to a standard ANVIS 18mm tube while the overall volume size has been reduced by 40%.
