  • Patent number: 9939659
    Abstract: 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.

  • Patent number: 9795281
    Abstract: An endoscope realized as either a borescope or a fiberscope including one or more fluid filled lenses is described. In an embodiment, the optical power of the fluid filled lenses may be adjusted to adjust the focal length associated with the endoscope. Thus, variable working distances are allowable while maintaining focus on an object in front of the endoscope. The endoscope may include a distance sensor, which is used to determine a distance between the endoscope and a sample. A processor may compare the measured distance to the current optical power of the one or more sealed fluid filled lenses. The processor may transmit signals to one or more actuators coupled to one or more sealed fluid filed lenses to change the optical power of the one or more sealed fluid filled lenses based on the comparison.

  • Patent number: 8817381
    Abstract: An optical and mechanical design of a sealed, non-round fluid-filled lens capable of providing variation of optical power. The fluid lens includes at least three optical components: at least one mostly rigid optical disc, at least one mostly flexible optical membrane and a layer of a transparent fluid that is in communication via a fluid channel with a reservoir of excess fluid contained in a reservoir that can be accessed to augment the fluid volume inside the fluid lens to change the power of the fluid lens. The fluid lens is capable of providing correction of spherical and astigmatic errors, and utilizes contoured membranes to provide for a substantially constant desired spherical power over a substantially full field of view of a user.
