Abstract
A fluorescence determining microscope scans the surface of a specimen with laser light. The fluorescence produced is split into components of different wavelengths, and the fluorescence of the respective wavelengths is determined.
Claims5
A microscope for scanning and determining the fluorescence of a cell comprised of a nucleus surrounded by cytoplasm, said microscope comprising:
- a laser light source for emitting light having a spot size smaller than the nucleus of the cell to be scanned;
- scanning means for directing the light from said light source onto the cell to spotwise irradiate the cell to produce fluorescence;
- means for splitting the produced fluorescence into components of different wavelengths;
- and
- detecting means for detecting the level of the fluorescence of the respective components.
