Red dot sight radius?

[Moose]

Is the sight radius of a red dot the length of the mount? A red dot seems to be as accurate as other sights. It performs as if it has a longer radius. Am I missing something as to why it may be as accurate?

Great question! I'd like to know the answer to that also...

Sight radius is the distance between the rear and front sight this term is used for open sights on hand guns and rifles with iron sights.

Basically, Red dot sights rely on two integral parts: The Light Emitting Diode (LED) and the two curved lenses, which reflect the light to pass through the reticle.

The special glass is specially coated so only light from the LED can pass through.

The glass will project the image onto the FOCAL PLANE to infinity and add the red dot to show you where your bullet may land once you shoot.

You can leave both eyes open when using a true red dot sight and you can adjust windage and elevation just like a scope. What is really nice about a true red dot sight is that wherever the dot is the bullet will go there if it has been sighted in.

Thanks for the good explanation, Chief55. I didn't know why the lens were coated. If I read into this correctly, the sight radius is from the LED to the lens of the focal plane. With the shorter radius, does that explain the stability of the dot versus the instability of a projected laser beam on the target? Does this also explain why a scope's crosshairs are stable? A new project is requiring me to think along these lines. I'll quite asking questions now.
