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...
