Abstract:
A microscope for observation of a sample that is dyed by a molecule having at least three electron states including a ground state and characterized as having a first light source for generation of a first light of a wavelength &lgr;1 which causes a transition of said molecule from the ground state to a first excited state, a second light source for generation of second light of a wavelength &lgr;2 which causes a transition of said molecule from a first excited state to a second excited state of higher energy level, a condensed light optical system for focusing of said first light and second light upon said sample, and an emitted light detector for detection of light emitted from said molecule;wherein the microscope is constructed such that light of said first light from said first light source is generated to form a multi-spatial mode condensation pattern and such that said condensed light optical system makes just a portion of the region of said condensed light pattern of the first light spatially overlap said condensed light pattern of the second light.
