Abstract
The invention relates to a lens, comprising a container () defining a volume (V) which is filled with a transparent liquid (), wherein the container () comprises a transparent and elastically deformable membrane () and a rigid member (), wherein the membrane () and the rigid member () delimit said volume (V), and a lens shaping element () that contacts the membrane () and defines an area () of said membrane (), which area () has an adjustable curvature for adjusting the focal length of the lens (). According to the invention, the lens () is configured to compensate a thermal expansion of the liquid () and/or a change of the refractive index of the liquid () due to an increased temperature of the liquid () in order to reduce an unwanted thermally induced change of the focal length of the lens ().
