Embodiment Construction

[0041] refer to figure 1 with 2A , respectively show a perspective view and a cross-sectional side view of the lens element 10 . The lens element 10 includes a housing 12 , two light-transmitting elastic solid lenses and a light-transmitting cover 14 . In the illustrated embodiment, the housing 12 is a simple annular structure into which the cover 14 is press fit. The two lenses nest together against the cover 14 . Other configurations of housing 12 are possible and will be described in detail below. The two elastic solid lenses and cover 14 together define an optical axis 16 .

[0042] The light transmissive cover 14 may be provided by a solid light transmissive material with or without optical power, or by a deformable membrane capable of exhibiting a curvature for defining a lens surface with optical power, such as in Figure 2B shown in . In the illustrated embodiment, the light-transmissive cover 14 is a solid sheet of glass.

Abstract

A lens element is provided that includes a housing defining a center bore and an optical axis, and a light transmissive cover coupled to the housing. A first elastic solid lens is disposed within the housing adjacent the light transmissive cover, and is characterized by a first thickness and a first durometer hardness. A second elastic solid lens is disposed in the housing adjacent to and substantially conforming to the first elastic solid lens, and is characterized by a second thickness and a second durometer hardness. The second lens thickness is less than the first lens thickness, and the second durometer hardness is greater than the first durometer hardness. In one embodiment, the first durometer hardness is less than OO60 as measured by the Shore method, and the second durometer hardness is in the range of A20 to A60 as measured by the Shore method.

Description

[0001] Cross References to Related Applications [0002] This application is based on the U.S. Patent Application No. 12 / 787,665 filed on May 26, 2010, whose invention title is "Solid Elastic Lens Element And Method Of Making Same". Priority is claimed to the above application and is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to a lens element for incorporation into an optical imaging system, and, more particularly, to a lens element comprising a plurality of solid elastic lenses. Background technique [0004] Many types of lenses, such as multifocal lenses and zoom lenses, typically employ one or more non-deformable (that is, rigid, such as glass or polycarbonate) lens elements along the The imaging axis moves. [0005] In recent years, motorless electrically responsive lens elements have drawn increasing attention from researchers and designers of optical systems. One type of motorless electro-resp...
