  • Patent number: 5381224
    Abstract: A scanning optical imaging or mapping system for macroscopic specimens is disclosed, which allows both confocal and non-confocal imaging to be performed in reflected light, photoluminescence, fluorescence and other contrast mechanisms. Several embodiments are disclosed, for use in photoluminescence mapping of semiconductor specimens, fluorescence scanning of gels used in gene sequencing, fingerprint detection, and other application areas.

  • Patent number: 5192980
    Abstract: A scanning optical microscope or mapping system for spectrally-resolved measurement of light reflected, emitted or scatttered from a specimen is disclosed, in which the spectrally-resolving element is integrated into the detection arm of the microscope or mapping system to result in good photon collection efficiency as well as good spectral and spatial resolution. A confocal version of the microscope is disclosed which will be of particular interest in fluorescence microscopy, and the non-confocal mapping system will be of particular interest in photoluminescence mapping of semiconductor wafers.
