Problems solved by technology
However, reflective scanning has the disadvantages of being unable to be coaxial, increasing system errors, and increasing system volume
The existing coaxial scanning technology generally has the disadvantage of being unable to perform linear scanning or the cost is too high. Therefore, it is necessary to design a lens that can realize high-precision coaxial linear scanning and has low production cost.

The invention discloses a lens capable of achieving laser transversely-moving type coaxial linear scanning. An incident plane of the lens is a plane, an outgoing plane is a curve plane meeting the following formula (please see the specification for the formula), in the formula (1), y is the length of the lens in the y direction, x is the position of the lens in the x direction, cs is a constant for limiting the shape of the lens, cy is a constant for limiting the thickness of the thinnest position of the lens in the y-axis direction, n0 is the refractive index of media where the lens is located, and n1 is the refractive index of materials of the lens. The lens is simple in structure, small in size and low in production cost, and when the lens moves back and forth in the direction perpendicular to an optical axis, high-precision laser transversely-moving type coaxial linear scanning can be effectively achieved.
Description
technical field [0001] The invention relates to a lens, in particular to a lens capable of realizing translational coaxial linear scanning of laser light, and belongs to the technical field of optical devices. Background technique [0002] With the development of science and technology and the needs of production, laser scanning technology has been widely used and developed, especially in the fields of laser scanning microscopic imaging, laser printing, laser cutting and other fields. [0003] Scanning mirror is a key part of laser scanning technology. At present, the common technology is mainly reflective scanning, among which rotating polygonal mirror is used for reflective scanning, and galvanometer scanning is the most widely used. However, reflective scanning has the disadvantages of being unable to be coaxial, increasing system errors, and increasing the volume of the system. The existing coaxial scanning technology generally has the disadvantages of being unable to p...
