Embodiment Construction
[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] like figure 1 As shown, a low-distortion optical system includes in sequence 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, a fifth lens 5, and a first lens Six lenses6.
[0028] The object plane side of the first lens 1 is a convex surface, the image plane side is a concave surface, and its focal power is negative;
[0029] The object plane side of the second lens 2 is a convex surface, the image plane side is a concave surface, and its focal power is negative;
[0030] The o...
