Available tubes for this model from Photonis:


Phosphor available in: black and white or green.



White Phosphor

The latest technological achievements 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

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
