Description

This Night Owl NOBG1 Tactical Night Vision Binoculars, are supplied complete with a head set, and is designed for hands free operation. It can also be hand held and has a magnification factor of 1X, so can happily be used whilst walking through the undergrowth. The unit has an inbuilt infra red illuminator and which makes it useful even in total darkness and uses a green image as it is the best colour for the human eye to see detail. It weighs just 440g and is powered by two LR1 (MN8100) batteries. (Not Included). 2 Year Manufacturing Warranty included. The binoculars can be removed from the head set to be handheld and there is a pinhole on the lens caps so the unit can be tested in ordinary lighting conditions to make sure everything is working before going into the darkness. The lens caps must always remain on when the binocular are in lit conditions, only remove them in the dark.

Performance Under Various Light Conditions

Complete Darkness

This night vision binocular works by amplifying available natural light and in complete darkness uses the Infrared illuminator like a flashlight, which is invisible to the human and animal eye.

Half Moon

When there is a half moon, it's amazing how much available light can be used by the units internal electonic intensifier tubes. Without the assistance of IR, you can recognize an adult sized object approximately 300 yards away.

Starlight (No Moon)

If using the binoculars without the infra red, the night vision binoculars recognize a man shaped object approximately 200 yards away.

Urban Environment (With Artificial Light Source)

Generally, street lights and headlamps will not damage the Electronic Transfer Tube as long as they are a safe distance away (usually around 30 yards) and not used as illumination for the use of the glasses. Do not point them directly into the light.

Night Vision works by light coming into the device from the objective lenses which is then focused onto the Image Intensifier tubes. The front of these tubes contain photo cathode which converts the light into electrons and the voltage from the battery transfers the electrons into the phosphorous screens, which in turn illuminate with an image. The image seen through Night Vision Binoculars isn't quite as clear as standard optical binoculars, as the screen can give light and dark spots which are caused by the Intensifier tube; this is quite normal. The image will fall away slightly to the edge as the centre of the image is the most intense, but this is corrected as much as possible by using top quality optics.

How Does it Work

The ambient light, such as the moon and stars is gathered by the lens of the Night Vision Monocular and then focused onto the image intensifier tube. The intensifier tube converts the gathered light into single electrons, which are then multiplied by a high voltage tube (17 kilovolt). These multiplied electrons strike a phosphorous screen in high numbers, which then activates the screens illumination and that's all there is to it, the amplified light signals can now be seen by the human eye.
