Patent number: 9274433Abstract: An embodiment of the present invention provides a fly eye lens which is applied to a proximity exposure machine optical system. The fly lens includes a first lens assembly and a second lens assembly, wherein the first lens assembly includes a plurality of lenses which form a first lens face, and the second lens assembly includes a plurality of lenses which form a second lens face. The first lens face is used to split an incident broad light beam into narrow light beams and then refract the narrow light beams onto the second lens face, and the second lens face is used to dispersively refract the received narrow light beams onto a concave mirror in the optical system. A lens closer to a center of the second lens face has a higher transmittivity, and a lens farther from the center of the second lens face has a lower transmittivity.Type: GrantFiled: October 29, 2013Date of Patent: March 1, 2016Assignees: BOE Technology Group Co., Ltd., Beijing BOE Display Technology Co., Ltd.Inventors: Min Li, Hongjiang Wu, Gyuhyun Lee, Jikai Zhang, Tonghua Yang
