REVIEW: NT940 Fusion-Bino Night Vision Device

03/09/2020By Redaktion
I'm sorry, I am only able to provide translations for text content and am unable to modify HTML elements, image sources, or links.

Night vision is a great invention. Two different techniques have now established themselves: low-light amplification and thermal imaging. Both have their respective technical advantages and disadvantages. Wouldn't it be great if there was a way to combine the best of both worlds? There is, and it's called "Fusion." We took a look at a Fusion night vision device with the help of IEA Mil-Optics.

It's called the NT940 Fusion-Bino night vision device. This is not a specially designed device, but at its core are three devices that are used together. Everything is laid out and disassembled.

On one hand, we have two NT940 night vision monoculars, also known as Mini 14. These are equipped with an Intense 4G Onyx image intensifier tube with white phosphor. Here are the technical details for all the nerds out there:

Technical Data Intense 4G Onyx (click me)
  • FOM: >1700
  • Max. output brightness: 4.0 to 8.0 cd/m²
  • Luminance gain (at 20 μlx): 7000 to 13000 cd/m²/lx
  • Resolution center: min. 64 lp/mm
  • Equiv. background illumin.: <0.35 μlx
  • Signal to noise ratio: >24.00

The two monoculars are connected by the Bino Bridge from IEA Mil-Optics.

This allows you to use the two monoculars like a binocular.

The devices can be individually folded to the side.

It is also practical when you fold the entire unit up, as this moves the center of gravity closer to the helmet. This is much more comfortable for your neck in the long run if you want to keep the NVG on the helmet but not use it.

On the other hand, to achieve the full Fusion, we need a thermal imaging device. This comes in the form of the Clip-IR.

This small thermal imaging device is simply attached to the appropriate mount, either on the side or underneath, of the low-light intensifier.

The thermal image is then projected in green tones in the middle of the low-light intensifier. When everything is correctly adjusted, the thermal image merges with the low-light image. This is an immeasurable advantage over using just one technology.

Especially in places where there is very little ambient light, this is an unbeatable advantage, as you can see in our video.

Such places include the interior of windowless rooms or simply very shaded areas in the wilderness. Where there is no ambient light, nothing can be amplified. Even with enemies behind bushes, the Clip-IR thermal imaging device can be a crucial advantage. Camouflage works with low-light amplification, but it's hard to hide from a thermal imaging device. We love technical data, so here are the specs for the Clip-IR:

Technical Data Clip-IR (click me)

  • 40° field of view
  • MicroCAM® temperature sensor
  • XTi Shutterless Technology®
  • 1 AA battery
  • 4½ battery life
  • Compatible with most night vision devices
  • Temperature imaging module: Thermoteknix MicroCAM - 384 x 288 25 μ with 40° field of view
  • Modes: Full thermal overlay, contour mode, phase pulse mode
  • Dimensions (W x H x D) 115 x 40 x 75 mm
  • Weight 150 g (including battery)

In total, the entire Fusion night vision device measures 15.3 x 12.7 x 14 cm and weighs 850 grams with batteries, so it's not lightweight. A counterweight on the back of the helmet is essential for such a device. A weight between 450 and 600g has proven to be good for us.

With the CLIP-IR, you can choose between three display modes. We have the classic White Hot and Black Hot modes, as well as an Outline mode. By pressing the dial on the device, you can switch between the two modes. One is always White Hot, and in the menu, you must decide if you prefer Black Hot or Outline mode as the second choice.
