![]() Miniature red dots are getting smaller and smaller every year and becoming a real option for CCW. These tiny red dot optics are designed and fitted as both pistol sights and backup sights for standard rifle optics. Miniature red dots are the smallest of the small. Standard rifle optics can often be mixed with a magnifier or night vision optic to increase the range and versatility of the platform. These optics often feature a 2 to 3 MOA red dot, a 25mm or more objective lens, and are designed for close to moderate range shooting. The vast majority of your red dots are tube based designs made for full sized firearms. There are several different kinds of red dot optics out there that all fill different roles or perform slightly differently. At longer ranges, the dot covers less of the target and makes seeing and hitting your target significantly easier Different Types of Red Dots 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. Since their invention in 1900, reflector sights have come to be used as gun sights on all kinds of weapons.This post was written for us by, a website that’s like having your very own gun obsessed buddy who’s really good at explaining stuff. ![]() Since the reticle is at infinity it stays in alignment with the device the sight is attached to regardless of the viewer's eye position, removing most of the parallax and other sighting errors found in simple sighting devices. Reflector sights employ some sort of "reflector" to allow the viewer to see the infinity image and the field of view at the same time, either by bouncing the image created by lens off a slanted glass plate, or by using a mostly clear curved glass reflector that images the reticle while the viewer looks through the reflector. These sights work on the simple optical principle that anything at the focus of a lens or curved mirror will look like it is sitting in front of the viewer at infinity.
