ATN Night Arrow6-2IA

ATN Night Arrow6-2IA
With the ATN Night Arrow 6-2IA ATN deliver a potent procuct, especially for the discerning marksman or cunning hunter. The viewer provides you with excellent observation, spotting and target performance on longer distances so you will hardly ever miss a target. Automatic Brightness Control (ABC) adjusts the brightness of the image automatically so the viewer yields the best picture quality in all lighting conditions. Compared to the ATN Night Arrow 6-2I, this visor has a higher resolution and therefore offers a clearer picture. ABC also protects the light-sensitive parts in the tube against overexposure. If the visor of the ATN Night Arrow6-2IA is extremely exposed, then the viewer will be automatically turned off to prevent damage to the system.

ATN series
The ATN Night Arrow is a series of several models in different price ranges. Equipped with the best optical instruments, tubes and offering excellent performance, this series is one of the best available on the commercial market. All the viewers are battery-powered. A full battery lasts 30 hours and, using the Low Battery Indicator, the viewer alerts you when the battery needs to be changed. The ATN Night Arrow is also available with a twofold and fourfold magnification.

Generation 2IA
The light amplification tube is the beating heart in this viewer. The difference between a first and a second generation unit is mainly the addition of a micro-channel plate, or MCP. The MCP works as an electron amplifier and is placed directly behind the photocathode. A photocathode is a negatively charged electrode in a night vision and has a photosensitive coating. From the moment light strikes it, the absorbed energy generates an emission of electrons. This process is caused by a photoelectric effect. Simply put, the MCP gives the electrons an extra push so that the second generation night vision provide a brighter and sharper image.

MOA or Click Value
The vertical height adjustment ensures that the target in the viewer coincides with the spot where the bullet strikes. The flight of the bullet is affected by gravity in an arc orbit effect, the rifle scope follows a straight line. To compensate for this effect, the viewer has a turning wheel for adjusting the height. Usually, the viewer is set to a certain distance, e.g. 25m. The adjustment wheel goes with clicks, so the adjustment per click is indicated as click value. The movement of the target point caused by one click of the dial is expressed in minutes (of degrees). A minute is 1/60th of a degree. In English this is called "Minute of Angle" or MOA. On a viewer it is often indicated what one click means for that specific model: 1/4 MOA, 1/8 MOA, so 1/240th or 1/480th of a degree.

Do the math
The distance to your goal is the radius of a vertical circle. With a distance of 10m, the circumference of a circle is 628 m (2 x pi x r). One degree displacement is 628:360 = 1.74m, one minute is 1.74:60 = 0.029m or 2.9cm. Divide this number by the amount of MOA, e.g. 1/4, and you have the vertical displacement of the target per click.
