Problems solved by technology

[0002] Today's imaging lenses with a viewing angle of more than 200 degrees have a large total length and aperture, which is difficult to meet the needs of miniaturization. Therefore, another imaging lens with a new structure is needed to meet the needs of large viewing angles, small aperture values, and small size at the same time. characteristics

Embodiment Construction

[0024] see figure 1 , figure 1 is a schematic diagram of the lens configuration of the first embodiment of the imaging lens according to the present invention. The imaging lens 1 includes a first lens L11, a second lens L12, a third lens L13, a fourth lens L14, a diaphragm ST1, a fifth lens L15, a sixth lens L16, The seventh lens L17, the eighth lens L18 and the optical filter OF1. During imaging, the light from the object side is finally imaged on the imaging surface IMA1.

[0025] The first lens L11 is a meniscus lens with negative refractive power and is made of glass material. The object side S11 is convex, the image side S12 is concave, and both the object side S11 and the image side S12 are spherical surfaces.

[0026] The second lens L12 is a meniscus lens with negative refractive power and is made of glass material. The object side S13 is convex, the image side S14 is concave, and both the object side S13 and the image side S14 are aspherical surfaces.

Abstract

The invention relates to an imaging lens, which sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a diaphragm, a fifth lens, a sixth lens, a seventh lens and an eighth lens from the object side to the image side along an optical axis. The first lens is a meniscus lens having negative refractive power. The second lens is a meniscus lens having negative refractive power. The third lens is a biconcave lens having negative refractive power. The fourth lens is a biconvex lens having positive refractive power. The fifth lens is a biconvex lens having positive refractive power. The sixth lens has a positive refractive power. The seventh lens has a negative refractive power. The eighth lens has a positive refractive power. The sixth lens and the seventh lens are glued to each other.

Description

technical field [0001] The invention relates to an imaging lens. Background technique [0002] Today's imaging lenses with a viewing angle of more than 200 degrees have a large total length and aperture, which is difficult to meet the needs of miniaturization. Therefore, another imaging lens with a new structure is needed to meet the needs of large viewing angles, small aperture values ​​and small size at the same time. characteristics. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an imaging lens that has the characteristics of large viewing angle, small aperture value and miniaturization, but still has good optical performance, aiming at the above-mentioned defects of the imaging lens in the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide an imaging lens, which sequentially includes a first lens, a second lens, a third lens, a fourth le...
