Embodiment Construction
[0011] The present invention will be further described in detail below in conjunction with the drawings.
[0012] Reference figure 1 : Optical lens with a focal length of 12mm, including the condenser group 1, the convex lens 2, the divergent group 3 and the image plane 4 arranged from left to right and the center line is on the same line. The external light passes through the condenser group 1, the convex lens in turn 2 and the divergence group 3 act on the image plane 4. The distance between the condensing group 1 and the convex lens 2 on the center line is 2.79 mm, and the distance between the convex lens 2 and the divergence group 3 on the center line is 4.85 mm. Among them, the adjustable focal length of the optical path structure is 12mm. As a result, the distance between the condenser group 1, the convex lens 2 and the divergent group 3 and the image surface 4 can be adjusted to facilitate the detection or shooting of objects at different distances and improve the applicab...

The invention discloses an optical lens with 12mm focal length. The optical lens comprises a light focusing group, a convex lens, a diverging group and an image surface that are orderly arranged from left to right while central lines thereof are placed on the same straight line; external light rays act on the image surface after orderly running through the light focusing group, the convex lens and the diverging group; the light focusing group and the convex lens are 2.79 mm apart on the central lines; the convex lens and the diverging group are 4.85 mm apart on the central lines. Via light focusing effects of the light focusing group, the light rays are further focused via the convex lens before finally being diverged via the diverging group; the light rays are enabled to uniformly act on the image surface, and requirements for light rays and pixels can be met; the optical lens with 12 mm focal length can be used on a detection device or a photographing camera, usage requirements for light rays can be met, and applicability can be improved.
Description
Technical field [0001] The invention belongs to an optical path, and particularly relates to an optical lens with a focal length of 12 mm. Background technique [0002] With the development of technology, people's requirements for various products are gradually diversified. Optical paths with different pixel requirements are used in various detection equipment and cameras, but most of the optical paths in the detection equipment and the optical paths in the camera cannot be used in common, which increases the difficulty of optical lens production. Summary of the invention [0003] The object of the present invention is to provide an optical lens with a focal length of 12 mm, which can solve at least one of the above-mentioned problems. [0004] According to one aspect of the present invention, there is provided an optical lens with a focal length of 12mm, which includes a condenser group, a convex lens, a divergence group and an image plane arranged in order from left to right, and...
