Abstract:
A variable focal length lens includes: a lens portion including a pair of light transmissive members, at least one of which is deformable, and a light transmissive liquid medium sealed between the pair of light transmissive members; and a liquid medium container including a chamber that communicates with the lens portion and is filled with the liquid medium, the liquid medium container causing the shape of the surface of the deformable light transmissive member or members to be changed by changing the volume of the chamber to adjust the amount of liquid medium with which the lens portion is filled.
