ATN Night Arrow2-2I

ATN Night Arrow2-2I
With the ATN Night Arrow 2-2I ATM deliver a potent procuct, especially for the discerning marksman or cunning hunter. The viewer provides you with excellent observation, spotting and target performance so you hardly ever miss a target. Automatic Brightness Control (ABC) adjusts the brightness of the image automatically so the viewer gives the best picture quality in all lighting conditions. ABC also protects the light-sensitive elements in the tube against overexposure. The ATN Night Arrow 2-2I is available in various designs and price ranges. Equipped with the best optics, tubes and excellent performance, this series is one of the best available on the commercial market. A feast for the eyes!

Gen 2+ Technology
Second Generation night vision. In a night rifle scope the image amplifying tube is the beating heart and this is also applies to the ATN Night Arrow 2-2I. 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.

Calculating the Click Value
The distance to your goal is the radius of a vertical circle. For a distance of 10m, the circumference of a circle is 628m (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.
