  • Patent number: 7391509
    Abstract: An analytical microscope provides both UV fluorescence imaging and spectroscopic analysis of a sample with use of the same light collection element (objective lens or other optical element). An incident UV light beam travels to the sample via a dark field illumination path about the periphery of the collection lens, with the collection lens then collecting the emitted light from the sample and forwarding it to an eyepiece and/or camera for viewing. The sample is also illuminated with a laser through the collection lens to generate Raman emissions, which are then collected through the same collection lens and provided to a spectrograph for wavelength identification. Use of the same collection lens for both imaging and spectroscopic analysis better ensures that any imaged regions of interest on the sample are the same as those being spectroscopically analyzed.
