ATN MARS4-2IA

ATN MARS4-2IA
ATN MARS4-2IA is part of ATN's Mars series which is inspired by ATN's quest for technical perfection and named after the Roman god of war. The ATN MARS Series Night Vision rifle scopes represent the very latest developments in the world of night vision. Like all other ATN series, this MARS series is equipped with the most advanced lens systems, partly computer-designed and equipped with lenses made from the toughest quality glass. With the ATN Mars series ATN have made a rifle scope with an ultra-fast light transmission and a resolution that exceeds the current military standard. The tubes for this product are hand-selected and are constructed from a single piece of aluminium, NASA-quality, and are inlaid with titanium components. The ATN MARS series is the only of its kind with a setting for the colour of the crosshairs, red or amber. This gives the user the choice to change colour depending on personal preference or tactical situation.

Marked improvement
Compared to the ATN MARS 4-2I this visor has a higher resolution and thus a clearer image. This version has a twofold magnification and provides you with excellent observation, spotting and target performance so you will be always target accurate. Automatic Brightness Control (ABC) adjusts the brightness of the image automatically so the viewer offers the best picture quality in all lighting conditions. ABC also protects light-sensitive parts in the tube against overexposure. If the visor is extremely exposed, then the viewer will be automatically turned off to prevent damage to the system. This ATN series offers a range of versions in different price ranges. All the viewers are powered by a battery. A 3V battery will last 55 hours and a 1.5V battery will last 40 hours. The night vision has a built-in low-battery indicator which will alert you when it is time to change the battery.

Generation 2IA
In this night vision, too, the light amplification tube is the metaphorical beating heart. The difference between a first and a second generation unit is mainly the addition of a micro-channel plate (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.

Click Value or MOA
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' (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.

Adding up
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. Multiply this number by the amount of MOA, e.g. 1/4, and you have the vertical displacement of the target per click.
