Abstract
An image stabilized optical system in which a pair of telescopic optical systems are arranged in parallel with each other to constitute binoculars. The telescopic optical system is composed of an objective, an eyepiece and an erecting prism located between the objective and the eyepiece. The erect prism is capable of having its incident light optical axis and its emanating light optical axis aligned with each other. The objectives and the eyepieces of the pair of telescopic optical systems are fixed to a casing of the image stabilized optical system, and the erect prisms are mounted on gimbals having two axes of rotation intersecting at right angle with each other. The two axes of rotation of the gimbals are included in a plane perpendicular to the main optical axes of the telescopic optical systems. The plane passes through a middle point of the distance from the objective to the eyepiece.
