White phosphor option for image intensifier tubes for night visionWhite Phosphor

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 and 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 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

Comparison sketch with dimensions of tubes

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%.
