Technical Field

[0001] The utility model relates to the technical field of optical components, in particular to a double-sided optical component capable of imaging through divergent laser irradiation. Background Art

[0002] Diffraction is a physical phenomenon. When light waves propagate through obstacles or objects, they will turn and diffuse when they encounter the surface of the object, forming some interference and refraction effects. Diffraction optical components are optical devices manufactured using this phenomenon. They can disperse, diffuse, reflect, and refract light, and are one of the keys to realizing the functions of optical equipment.

[0003] Diffractive optical elements are a type of optical device that modulates the incident phase through a relief structure on the surface to obtain a light spot of arbitrary shape on the output surface. Due to the additional assembly space for the lens, the structure will be relatively large, and it will be difficult to adapt to many small-volume products. Because focusing lenses are required, the cost will also be relatively high. At present, when the double-sided optical component structure is coordinated to achieve light beam adjustment, the two need to be limited and fixed, but they are fixed with adhesive materials and cannot be reused after disassembly, which causes a certain degree of waste of optical components. At the same time, the connection force and fixation between the structures cannot be determined.
