Abstract
An optical device for stabilizing an image of an objective lens against an unexpected vibration is disclosed. A pair of transparent parallel-plane plates are supported by a support member, an optically transparent material is held in a space defined by the pair of parallel-plane plates by a deformable connecting member, a reinforcement member made of a harder material than that of the support material is provided at a portion of the support member, and a drive force is applied to the pair of parallel-plane plates through the reinforcement member.
Claims15
An optical device comprising:
- a transparent and soft material;
- a pair of transparent plates for supporting said material;
- a frame that surrounds a periphery of each plate;
- a flexible connecting member for connecting said frames to define a space in which said transparent and soft material is filled;
- a reinforcement member formed in each of said frames that is harder than said frames;
- and
- means for applying a driving force to at least one of said frames directly through said reinforcement member.
An optical device comprising:
- a pair of transparent parallel-plane plates;
- a support member for supporting each of said pair of parallel-plane plates;
- an optically transparent material held in a space defined by said pair of parallel-plane plates;
- a deformable connecting member for connecting said pair of parallel-plane plates and for holding said optically transparent material in said space;
- a reinforcement member made of a harder material than the material of said support member and formed adjacent to a portion of said support member;
- and
- drive means for applying a drive force to each of said pair of parallel-plane plates through said reinforcement member.
An optical device for varying an angle formed by a pair of transparent elements by a driving force of drive means, said device comprising:
- a flexible connecting member;
- a pair of composite members for respectively supporting said transparent elements, each composite member of said pair of composite members comprises both a support member to be connected with said flexible connecting element and a reinforcement member, which is made of a material harder than said support member, wherein at least one of said reinforcement members is both connected with one of said support members and said drive means;
- and
- a transparent member filled within a cell that is formed by said pair of transparent elements and said flexible connecting member.
