An optical device (10) comprises: a translucent body (1) that transmits light of a prescribed wavelength; a housing (2) that holds the translucent body; a piezoelectric element (5); a first vibration body (3) that vibrates the translucent body by the vibration of the piezoelectric element; and a second vibration body (50) that has an attenuation coefficient smaller than the attenuation coefficient of the translucent body and that is in contact with the translucent body to vibrate together with the translucent body.

    L'invention concerne un dispositif optique (10) comprenant : un corps translucide (1) qui transmet la lumière d'une longueur d'onde prescrite ; un boîtier (2) qui maintient le corps translucide ; un élément piézoélectrique (5) ; un premier corps de vibration (3) qui fait vibrer le corps translucide par la vibration de l'élément piézoélectrique ; et un second corps de vibration (50) qui a un coefficient d'atténuation inférieur au coefficient d'atténuation du corps translucide et qui est en contact avec le corps translucide pour vibrer conjointement avec le corps translucide.

    光学装置(10)は、所定の波長の光を透過させる透光体(1)と、前記透光体を保持する筐体(2)と、圧電素子(5)と、前記圧電素子の振動によって前記透光体を振動させる第1振動体(3)と、前記透光体の減衰係数よりも小さい減衰係数を有し、前記透光体に接して前記透光体とともに振動する第2振動体(50)とを備える。
