ABSTRACT:
An optical device functioning as a variable apex angle prism and suitable to be incorporated in an image stabilizing apparatus for an optical apparatus is constituted by a pair of transparent circular plates disposed oppositely spaced from each other, a connecting member attached to the circular plates so as to define a closed space in combination with the circular plates and deformable under application of an external drive force, and a transparent substance disposed within the closed space. The transparent substance comprises at least one compound selected from the group consisting of polyether-modified organopolysiloxane, polyether alcohol-modified organopolysiloxane and fluorine-containing compounds.
