Telescopic Sight

A telescopic sight, commonly called a scope, is a sighting device that is based on an optical refracting telescope. They are equipped with some form of graphic image pattern (a reticle) mounted in an optically appropriate position in their optical system to give an accurate aiming point. Telescopic sights are used with all types of systems that require accurate aiming but are most commonly found on guns. Other types of sights are iron sights, reflector (reflex) sights, and laser sights.

Famous quotes containing the word sight:

    It was always startling to discover so plain a trail of civilized man there. I remember that I was strangely affected, when we were returning, by the sight of a ring-bolt well drilled into a rock, and fastened with lead, at the head of this solitary Ambejijis Lake.
    Henry David Thoreau (1817–1862)
