Abstract
A liquid lens can include two or more liquids enclosed in a chamber. The liquid lens can be configured to reduce the chromatic aberration produced when the meniscus formed at the interface of two of the liquids is tilted. This can be accomplished in a number of ways including selecting the liquids to maximize the refractive index difference and minimize the Abbe number difference.
