Abstract:
A confocal microscope for optical detection of an observation volume, comprising:a light source generating excitation light,a dichroic mirror reflecting the excitation light impinging thereon from the light source,an objective lens arrangement with a mechanical aperture connected thereto receiving the excitation light reflected by the dichroic mirror and focusing the light on the observation volume, andan observation lens arrangement receiving light coming from the observation volume and passing through the dichroic mirror,wherein, between the dichroic mirror and the mechanical aperture of the objective lens arrangement, a deflection mirror arrangement is located having a first planar deflection mirror on the side of the objective lens, andwherein said first deflection mirror oscillates about the normal position and deflects said reflective excitation light under any angle of incidence, so that it impinges at a substantially common part within said mechanical aperture.
