Claim 16:
17. A method for imaging a sample, the method comprising
transmitting input optical radiation from a flexible lightguide through a lens assembly comprising an electrowetting variable-focus lens element according to claim 15, thereby focusing the radiation on or in the sample;
transmitting radiation emanating from the sample in response to the optical radiation to the flexible lightguide through the lens assembly; and
transmitting the emanated radiation to a photodetector; then
changing the focal length of the variable-focus lens element, the focal position of the variable-focus lens element, or both by changing one or more voltage biases on one or more of the plurality of separately-addressable first electrodes, and then
repeating the transmitting of the optical radiation from the flexible lightguide through the lens assembly, the transmitting of the radiation emanating from the sample in response to the optical radiation, and the transmitting of the emanated radiation to the photodetector.
