Scanning microscope system
View Patent ↗A scanning microscope system includes an optical microscope observation unit that irradiates the sample with excitation light, and forms an optical image from fluorescence emitted from a sample. The system also includes a scanning map creator and a flying spot scanning observation unit. The scanning map creator creates a scanning map indicating a scanning region in which a substance to be scanned exists in the sample, based on brightness of pixels of the optical image. The flying spot scanning observation unit scans the scanning region of the sample with laser beam, and forms a scanning image based on fluorescence emitted from the sample.
