Abstract

The invention discloses an ultra-light digital sighting telescope optical system, which adopts an organization structure of an objective lens group, a CMOS image sensor, an OLED display and an eyepiece group, wherein the objective lens group comprises a first objective lens, a second objective lens, a third objective lens and a fourth objective lens; the third objective lens is an aspheric element, the first surface of the third objective lens is a spherical surface, and the second surface of the third objective lens is an aspheric surface; the eyepiece group comprises a first eyepiece lens and a second eyepiece lens, and two surfaces of the second eyepiece lens are aspheric surfaces; and the front surface of the first objective lens and the rear surface of the second eyepiece lens are plated with conductive films, and the other surfaces of an optical piece are plated with antireflection films. The objective lens group and the eyepiece group in the ultra-light digital sighting telescope optical system adopt aspheric design, so that light weight is realized, and the zero stability of a sighting telescope is improved.

Description

technical field

[0001] The patent of the invention belongs to the technical field of optical instruments, and specifically relates to an optical system of an ultra-light digital sight. Background technique

[0002] The digital sight is a sighting equipment that integrates optics, electronics, software and other technologies. With the development of scientific research and the increase of military technology requirements, higher and higher requirements are put forward for the application of military sight and sight electro-optical systems. However, the existing aiming system has complex structure, large volume, high weight, and relatively short exit pupil distance, generally 20-30mm, which is not suitable for observers to quickly search and identify targets, and can no longer meet the requirements of use. Contents of the invention

[0003] In order to overcome the shortcomings of the existing sight system, the purpose of the present invention is to provide an ultra-light d...

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, an ultra-light digital sight optical system of this embodiment adopts the organizational structure of objective lens group + CMOS image sensor + OLED display + eyepiece group, and the technical design is mature and reliable. The scene is projected to the CMOS through the optical image generated by the objective lens group On the image sensor, the video is generated and processed by the image processing board and then transmitted to the OLED display, and then the image is displayed on the OLED display, and the human eye observes it through the eyepiece group.

[0031] In this embodiment, the objective lens group includes an objective first lens 1, an objective second lens 2, an objective third lens 3, and an objective fourth lens 4;

[0032] The radii of curvature of the first lens 1 of the objective lens are...
