High-magnification compact telescopic sight optical system

Abstract

The invention discloses a high-magnification compact telescopic sight optical system. The high-magnification compact telescopic sight optical system comprises an objective lens group, a focusing lensgroup, a field lens, a relay lens group, a dividing plate and an eyepiece group which are arranged on the same optical axis, infinite parallel light passes through a chromatic aberration correction objective lens group from the object surface to form converging light, a primary inverted image point is converged through the focusing lens group, the height of beams is greatly compressed by formed divergent light passing through a high-focal-power field lens, the converging light is formed again, through the relay lens group, an image converged to a dividing line of the dividing plate forms a secondary erect image point, and finally, human eyes observe scenes being subjected to angular magnification through a wide-view-field eyepiece group in the structural form of an Elfer eyepiece. According to the high-magnification compact telescopic sight optical system, an inner focusing structural form is adopted, the sealing performance is very good, close observation can be achieved, a replication system is avoided, the optical axis consistency of the dividing plate is very high, a positive real image is directly formed for the human eyes, the ability to collect light energy is high, and themagnifying power is high.

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...
