FLUID LENS ASSEMBLY |
摘要 |
A non-round fluid lens assembly includes a non-round rigid lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity so as to change the optical power of the fluid lens assembly. In an embodiment, a front surface of the non-round rigid lens is aspheric. Additionally or alternatively, a thickness of the flexible membrane may be contoured so that it changes shape in a spheric manner when fluid is transferred between the cavity and the reservoir. |

1. A fluid lens assembly, comprising:
a non-round rigid lens having a back surface and a front surface, the front surface having a rotationally symmetrical aspheric correction; a flexible membrane coupled to the back surface of the non-round rigid lens, such that a cavity is formed between a front surface of the flexible membrane and the back surface of the rigid lens; and a reservoir in fluid communication with the cavity between the front surface of the flexible membrane and the back surface of the non-round rigid lens, such that a fluid is transferable between the reservoir and the cavity to change the optical power of the fluid lens assembly, wherein the front surface having a rotationally symmetrical aspheric correction at least partially reduces an optical error, and
wherein the rotationally symmetrical aspheric correction does not exceed 0.18 D. |
