Red Dot Sight – Everything You Need to Know About the Red Dot Sight
We can say the red dot sight is the best advance in gun shooting since the early 1900’s. This device gives a level of precision and simplicity of operation that is impossible to achieve with an iron sight.
How does it work?
This sight has a concave lens with a very thin metallic coating that reflects red light and transmits other colors without restraint. The dot reticle is a light reflection that emits diode and is mounted inside the sight tube, resulting in a red dot that is projected on the target.
What makes it great?
Red dot sights are great mainly because of their polarized filter, which is attached to the far end of the sight and works as a variable light filter to regulate the target’s brightness no matter the dot’s intensity.
The polarized filter is actually two polarizing filters that rotate independently; these are sheets of transparent plastic with microscopic parallel lines engraved in them. The lines diminish the amplitude of light waves that reach the filter and that vibrate in different directions from the line’s.
The second filter’s lines can be parallel, perpendicular, or at any other angle regarding the first filter, since it rotates separately.
– The dot is not projected at the same seeming distance as the target; it is focused at about 30 feet, no matter the distance to the aim, which is good because then the eye centers on the 30 ft. projected reticle instead of on the target and the fast appearing bullet holes.
– One important piece of information you should know is that the dot’s size can only be determined by your eye; the manufacturer’s specifications are normally inaccurate.
– There is parallax in all dot sights because of the nature of the sight’s design itself. Parallax is the error that happens when one of two parallel vectors is used as reference for the other.
What happens with the dot sight is that the reflecting lens is optimized to reflect the LED’s image down the center of the tube into your eye, when the pistol is incorrectly held and the shooter sees the dot close to the tube’s edge, it will not be really pointed at the correct target. This is why the reflecting lens is concave, to try to correct this; however, this is not enough.
