Abstract

The present invention provides an internal red dot aiming structure and method. The invented internal red dot aiming structure and method mainly is applied on a rapid aiming device. According to the invention, a point light source is emitted between a tilt planar eyepiece lens and a concave objective lens, and the point light source irradiates towards the eyepiece lens so that the point light source produces a reflection on the eyepiece lens to form a virtual point light source on the focal point of the objective lens. Thus, the virtual point light source is projected on the objective lens and then emitted out in parallel in order to simulate a point light source emitted from a far distance in parallel, thereby achieving the objective of marking an internal red dot in the aiming device and reducing the length of the aiming device, while enlarging the objective lens. As a result, the whole view is wider and no distortion and diffusion of the image will occur.
