Patent number: 11686930Abstract: A scanning microscope includes an objective arranged in an illuminating beam path and configured to focus an illuminating light bundle onto a sample. A scanning unit is arranged upstream of the objective in the illuminating beam path and configured to deflect the illuminating light bundle in such a way that the illuminating light bundle focused by the objective executes a scanning movement. A detection unit is arranged in a detection beam path and configured to receive a detection light bundle not deflected by the scanning unit. For spectral influencing of the detection light bundle, the detection unit contains a spectrally selective component which has an active surface with a spectral edge which varies with a location of incidence of the detection light bundle on the active surface. The active surface is arranged in the detection beam path at a location of the image of the objective pupil.Type: GrantFiled: September 11, 2020Date of Patent: June 27, 2023Assignee: LEICA MICROSYSTEMS CMS GMBHInventors: Hilmar Gugel, Felix Neugart, Ingo Boehm
