A confocal microscope for optical detection of an observation volume includes a light source, a dichroic mirror, and an objective lens arrangement which further includes a mechanical aperture and an observation optic arrangement. Between the dichroic mirror and the objective lens arrangement, a deflection mirror arrangement is located having a planar deflection mirror on the side of the objective which is arranged to oscillate about a normal position. The objective-side deflection mirror is designed so that, upon oscillation of the objective-side mirror, optical axes of the reflected excitation light intersect in a substantially common intersection in the area of the mechanical aperture of the objective lens arrangement, and so that, when the objective-side deflection mirror is in its normal position the oscillation axis of the objective-side deflection mirror coincides with the line of intersection of the plane in which the objective-side deflection mirror lies, and a plane extending through the common intersection of the optical axes of the reflected excitation light which is perpendicular to the optical axis of the reflected light.
