Abstract: The ophthalmic optical system is configured to apply an angular scanning light ray to an eye. M=|ωout/ωin| is defined, where ωin represents an angle between an incident light ray to the ophthalmic optical system and an optical axis of the ophthalmic optical system, and ωout represents an angle between an exiting light ray exiting from the ophthalmic optical system toward the eye and the optical axis. The ophthalmic optical system satisfies a conditional expression Mpar

Abstract: An objective lens (OL) comprises, disposed in order from an object: a positive lens (L11); a negative meniscus lens (L12) cemented to the positive lens (L11) and having a concave surface facing the object; and a positive meniscus lens (L13) having a concave surface facing the object; wherein the objective lens satisfies following conditional expressions 2.03≤n1m≤2.30 and 20≤ν1m, where, n1m: a refractive index of the negative meniscus lens (L12) with respect to a d-line, and ν1m: an Abbe number of the negative meniscus lens (L12).
