Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0021] Such as figure 1 As shown, the large-aperture, ultra-wide-angle, high-pixel, short-total-length optical system is arranged in order from the object plane to the image plane 8 along the optical axis: a first lens 1, a second lens 2, a third lens 3, a fourth lens 4, and a fifth lens. Lens 5, and sixth lens 6.

[0022] The object surface side of the first lens 1 is a convex surface, the image surface side is a concave surface, and its refractive power is negative;

[0023] The object surface side of the second lens 2 is a convex surface, and the image surface side is a...

Abstract

The embodiment of the invention discloses a large-aperture, ultra-wide-field, high-pixel and small-overall-length optical system. A first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens are sequentially arranged along an optical axis from the object plane to the image plane; the fourth lens and the fifth lens are glued to form a combined lens, and the focal power of the combined lens is positive. Besides, the embodiment of the invention provides a camera lens. The large-aperture, ultra-wide-field, high-pixel and small-overall-length optical system is mainly composed of the six lenses, the number of the lenses is small, the structure is small, and the size is small. The different lenses are combined, the good optical performance of the large aperture, the ultra wide field, the high pixel, the small overall length and the like is achieved, and when the large-aperture, ultra-wide-field, high-pixel and small-overall-length optical system is applied to an automobile data recorder and other imaging equipment, a high-definition picture can be shot.

Description

Technical field: [0001] The invention relates to an optical system and an applied lens, in particular to an optical system and lens applied to imaging equipment such as a driving recorder. Background technique: [0002] Existing optical systems and lenses used in imaging equipment such as driving recorders have defects such as blurry shooting pictures under low light conditions at night, unclear license plates, or complex lens structures and high costs to achieve large aperture effects. Summary of the invention: [0003] In order to overcome the problem of blurry shooting images in the existing optical system or lens, one aspect of the embodiments of the present invention provides a large aperture, ultra-wide-angle, high-pixel, and short-length optical system. [0004] A large-aperture, ultra-wide-angle, high-pixel, short-total-length optical system is provided with a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens in order from the object surf...
