  • Method of scanning a sample with a light beam focused by a microscope objective lens and scanning light microscope
    Patent number: 11513327
    Abstract: Upstream a microscope objective lens, a polarization direction of a light beam is tilted with a first electro-optical deflector between a first polarization direction with which the light beam is deflected by a first polarization beam splitter by a first angle and a second polarization direction with which it is deflected by a second angle. With a second electro-optical deflector, the polarization direction of the light beam is tilted between a third polarization direction with which the light beam is deflected by a second polarization beam splitter by a third angle and a fourth polarization direction with which it is deflected by a fourth angle. By rotating the polarization direction of the light beam by means of the first and second electro-optical deflectors in a coordinated way the light beam is tilted about a fixed point in a pupil of the objective lens.
