A high magnification compact telescopic sight optical system

Abstract

The invention discloses a high-magnification compact telescopic sight optical system, which comprises an objective lens group, a focusing lens group, a field lens, an image transfer lens group, a reticle and an eyepiece group on the same optical axis, and is parallel to infinity. The light passes through the chromatic aberration correction objective lens group from the object surface to form a converging light, which is converged into an inverted image point through the focusing lens group, forms a divergent light, and passes through a high-power field lens to greatly compress the beam height, and then forms a converging light again and passes through the image transfer lens group. Make the image of the reticle converged on the reticle to form a secondary positive image point, and finally the human eye observes the scene enlarged by the angle through the large field of view eyepiece group of the Elver eyepiece structure. The present invention adopts an internal focusing structure, which has very good sealing performance, and can be observed at a close distance without a deflection system. The consistency of the optical axis of the reticle is very high, and it can directly form a positive real image for the human eye and the ability to collect light energy. Strong, high magnification.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a high-magnification compact telescopic sight optical system. Background technique [0002] As an optical device that can be directly used by the human eye, the white light sight has very important and irreplaceable application value. It does not need power supply and is portable, so it has a very wide application environment. [0003] Telescopic sights are divided into Kepler-type, Galileo-type, collimating and holographic sights and other types. Kepler-type telescopic sights are small in radial size and easy to install and use. It can zoom in and observe the target, and has high aiming accuracy; the Galileo telescopic sight has a simple structure, but low transmittance and small magnification; the collimating telescopic sight is small in size and light in weight, but has a large loss of light. The aiming accuracy is low; the holographic sight has a complex structu...
