The invention discloses an electrowetting-type variable-focus liquid lens comprising a gradient index material and belongs to the technical field of optics. The main characteristics are that the front and back surfaces of the liquid lens adopt a plano-convex lens and a plano-concave lens which are made of the gradient index materials respectively and are easy to process; and through reasonably selecting gradient index coefficients A, B and C matched with the two lenses, spherical aberration and chromatic aberration are compensated, and thus the imaging quality of the liquid lens is improved. Besides, a cavity of the liquid lens is made of Kovar materials, so that electrodes can be led out from the cavity directly without plating metal electrodes on the inner wall of the cavity, and the cavity and the two lenses can be welded by utilizing a high-frequency welding method, and thus the seal performance of the liquid lens is effectively improved. The liquid lens overcomes the defect that a common liquid lens can only change focal length but cannot eliminate chromatic aberration and aberration simultaneously; and the liquid lens has the advantages of being excellent in image quality, being capable of forming an optical system independently in application, being small in size, and not needing other elements to participate in imaging.
