This invention teaches a telescopic gun sight with a reticle placed at the first focal plane such that the apparent size of the reticle remains substantially invariant when the sight's magnification is changed. According to one embodiment, a telescopic gun sight comprises an objective lens, a magnification-invariant reticle, an image relay means with variable magnification, and an eye piece. The magnification-invariant reticle is designed in accordance to the invention such that its apparent size is not affected by change in the sight's magnification. This invention combines the benefits of telescopic gun sights with first focal plane reticle and second focal plane reticle in a single design. |
