Embodiment Construction
[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0010] refer to figure 1 : An optical lens with a focal length of 50mm, including the first lens 1, the second lens 2, the third lens 3, the fourth lens 4 and the image surface 5 arranged in sequence from left to right, and the centers of each lens and the image surface are on the same line Above, the center thicknesses of the first lens 1, the second lens 2, the third lens 3 and the fourth lens 4 are 6.73mm, 4.52mm, 7.16mm and 6.45mm respectively, the first lens 1, the second lens 2, the third lens The distances between the adjacent lenses of the lens 3 and the fourth lens 4 are 0.1mm, 1.58mm and 14.92mm in turn, the first lens 1 is a convex lens, and the radii of the mirror surfaces on the left and right sides are 24.63mm and 327.6mm respectively, and the second lens 2 The mirror surfaces on the left and right sides of the lens are convex to the left, and ...

The invention discloses an optical lens with a focal length of 50 mm. The optical lens comprises a first lens body, a second lens body, a third lens body, a fourth lens body and an image surface which are arrayed in sequence from left to right, wherein the centers of all the lens bodies and the image surface are located on the same straight line; the centers of the first lens body, the second lens body, the third lens body and the fourth lens body respectively have thicknesses of 6.73 mm, 4.52 mm, 7.16 mm and 6.45 mm, and the first lens body, the second lens body, the third lens body and the fourth lens body have the focal length of 50 mm. External light rays can finally uniformly work on the image surface through gathering and dispersing effects of all the optical lens bodies on the external light rays, so that the pixel can reach 2,000,000; and therefore, the optical lens with the focal length of 50 mm can be applied to detection equipment or a photographic camera, and the applicability is improved.
Description
technical field [0001] The invention belongs to an optical path, in particular to an optical lens with a focal length of 50 mm. Background technique [0002] With the development of science and technology, people's requirements for various products are gradually diversified. The optical paths required by different pixels are used in various testing equipment and cameras, but most of the optical paths in the testing equipment and the optical paths in the camera cannot be used in common, which increases the difficulty in the production of optical lenses. Contents of the invention [0003] The object of the present invention is to provide an optical lens with a focal length of 50 mm, which can solve at least one of the above problems. [0004] According to one aspect of the present invention, provide a kind of focal length and be the optical lens of 50mm, comprise the first eyeglass, the second eyeglass, the third eyeglass, the fourth eyeglass and the image surface arranged ...
