ATN Night Arrow2-CGTI

ATN Night Arrow 2-CGTI
With the ATN Night Arrow 2-CGTI ATN have designed a magnificent product, especially for the discerning marksman or skilled hunter. The viewer provides you with excellent observation, spotting and target performance so you will hardly ever miss a target. Automatic Brightness Control (ABC) adjusts the brightness of the image automatically so the viewer offers the best picture quality in all lighting conditions. A full battery lasts 30 hours and the Night Arrow 2-CGTI warns you when it is time to change the battery.

Additional information
Compared with the Night Arrow 2-2IA this visor has a higher resolution. ABC also protects the light-sensitive elements in the tube against over-exposure. If the visor is extremely exposed, then the viewer is automatically turned off in order to prevent damage to the system. The NightArrow consists of a series of several models in various price ranges. Equipped with the best optics, tubes and offering excellent performance, this ATN series is one of the best available on the commercial market.

CGTI Generation
In a night vision the image intensification tube is the heart and this is no different in the Night Arrow 2-CGTI. The difference between a Gen 2 + and a Gen CTGI unit lies in the use of the type of 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 provides a brighter and sharper image. Generation CTGI is a refinement of the Gen 2 + and uses compact 18mm Multi-Alkali MCP Image Intensifiers. This improvement is responsible for an exceptionally clear and bright picture.

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 in 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 MOA
The distance to your goal is the radius of a vertical circle. For a distance of 10m, the circumference of a circle 628m is (2 x pi x r). One degree of 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.
