Abstract
A collimator gunsight has a collimator lens, a transparent graticule in the focal plane of the lens, and a window behind the graticule. A small artificial light source is positioned between the graticule and the window but does not obscure the ambient light entering the window from illuminating the graticule. The graticule pattern has a first portion through which light from the artificial source can pass into the aperture of the collimator lens, and a second portion which diverts, e.g. by refraction, ambient light entering the window and by-passing the artificial source so as to fill the aperture of the lens.
