Typically bigger dots are quicker to see and get on target, smaller dots are better for shooting at moderate distances. The size of a red dot is measure in MOA, and that size is controlled by an aperture hole in front of the led. This allows you to see your reticle and see through your optic, but someone on the other side of the optic cannot see your reticle. That glass reflects the light from an LED onto it, creating your reticle. To break it down simply an LED shines a beam of light onto a specially coated, slightly angled piece of glass. This prevents other light from disrupting your reticle. That spherical reflector has a special coating that only reflects red light. The idea is simple you utilize plates of glass and a light.Ī red dot has a spherical mirror that reflects the light emitted from an LED of its axis focus. Red dots uses the same principle as an old magician’s trick known as Pepper’s Ghost. How Do They Work?Ī simple optic should work simply, right? Well, there is a little technological magic to it. Like all technology, they’ve shrunk in size and gotten to the point where they range from full-sized rifle optics to optics small enough for duty handguns. Invented in the mid-70s red dots have come a long way in the past 40+ years and have especially seen major advancements in battery life, clarity, and quality in the past 10 years. This is why we don’t call them scopes, but red dots, or optics, or red dot optics. Red dot optics are 1x optics and do not feature a built-in magnification. Because of how simple and straightforward a red dot is, it’s one of the best tools for training new shooters. Well sometimes the dot can be green, but those are still known as red dots just for simplicity’s sake. If you can’t tell by the name, these optics use a red dot as the reticle. It is a very simple optic that uses a simple reticle to do a simple job. What is a Red Dot Optic?Ī red dot sight is an optic designed to be used at close to moderate ranges.
