Abstract

Methods of forming a tunable focal length lens and an optical filter are disclosed. The tunable focal length lens may have varying focal lengths due to liquids within micro-channels which may cause varying cross-sectional areas of the micro-channels. The tunable focal length lens may have variable force. The tunable focal length lens may have a variable refractive index. The optical filter may have varying wavelengths due to dyes within the micro-channels. An apparatus incorporating an aspherical lens is also disclosed.
