3D interactive lens

Abstract

The invention provides a 3D interactive lens. A micro imaging lens system formed by five groups of lenses is arranged. The 3D interactive lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens from an object side to an image side successively. The first lens has a negative refraction power and the objective side is a convex surface; the second lens has positive fraction power and the image side of the second lens is a convex surface; the third lens has a negative refraction power and the image side of the third lens is a concave surface; the fourth lens has a positive refraction power and the image side of the fourth lens is a convex surface; and the fifth lens has a negative refraction power and the object side of the fifth lens is a convex surface and the image side is a concave surface. The lens meets the relations: 0<(R3+R4) / (R3-R4)<1.2, and 7<T12 / T23<25, wherein R3 and R4 respectively indicate curvature radiuses of the object side and the image side of the second lens, T12 indicates a distance between the first lens and the second lens at the optical axis, and the T23 indicates the distance between the second lens and the third lens at the optical axis. According to the invention, On the basis of configuration of the lens, advantages of small aperture and miniaturization and the like can be realized on the premise that wide angle and high resolution ratio are guaranteed. Meanwhile, the heat difference can be effectively eliminated and distortion can be well corrected.

Description

Technical field [0001] The invention relates to a 3D interactive lens, which is a miniature imaging lens system composed of five groups of lenses. Background technique [0002] At present, with the development of CMOS chip technology, the pixel size of the chip is getting smaller and smaller, and the requirements for the imaging quality of the matching optical system are getting higher and higher, and the size of the optical lens of the mobile phone or digital camera is getting smaller and smaller; With the development of technology, 3D interactive lenses have also been produced. Nowadays, 3D interactive lenses have begun to integrate the digital three-dimensional world into our daily lives. Generally, thin lenses cannot meet the high-quality resolution requirements of 3D lenses due to their small size and fewer lenses. This will inevitably increase the number of lenses and increase the total optical length of the lens, making it difficult to achieve miniaturization. The inventi...

Problems solved by technology

Due to the small size and the relatively small number of lenses, ordinary thin lenses cannot meet the high-quality analysis requirements of 3D lenses. This will inevitably increase the number of lenses, and at the same time increase the total optical length of the lens, making it difficult to have the characteristics of miniaturization

The invention patent with the publication number "CN103477264" and the title "Image Capture Lens and Image Capture Equipment" includes five lenses, specifically the first lens with negative refractive power, the second lens with positive refractive power, and the negative refractive power The third lens with positive refractive power, the fourth lens with positive refractive power, and the fifth lens with negative refractive power. With such a structure, although high resolution and miniaturization are achieved, distortion and thermal difference are not effectively controlled. , the image quality is reduced, and the overall length of the lens is also a bit long, and it can be shortened
