Abstract:
A binocular having a hand-vibration compensation system for compensating trembling of images due to a hand-vibration applied to said binocular, said binocular comprising:a pair of telescopic optical systems;first and second compensation optical systems respectively provided in said pair of telescopic optical systems, optical axes of said pair of telescopic optical systems intersect said first and second compensation optical systems, respectively; andan arm rotatable about a rotation axis extending in parallel with said optical axes of said pair of telescopic optical systems, at least one optical element included in each of said first and second compensation optical systems being held at each end of said arm, said rotation axis being located between said optical axes of said pair of telescopic optical systems, said arm being substantially equally balanced at said rotation axis; andan actuator that drives said arm to rotate about said rotation axis in accordance with a hand-vibration applied to said binocular.
