    I would like to know how to calculate mirror beam dispersion in the Earth's atmosphere at sea level. Let's presume average pollution levels and a clear day. For example, if I have a circular mirror with one inch diameter, how wide will the beam be at a distance of 1,000 meters?

    Thanks in advance!

    It it a flat mirror, concave, convex, parabolic, hyperbolic, or any of another million shapes? How far away is the light source. What is it's dispersion?

    It's a flat glass mirror. The light source is the sun. No idea what the mirror's dispersion is. I could empirically find out.
