  • Multi-technique imaging system using vertical motion of stage to switch imaging techniques
    Patent number: 8933384
    Abstract: A system for and method of performing multi-technique imaging. Such multi-technique imaging system includes a surface for supporting a specimen and at least two illumination sources for producing light radiation. The system also includes a plurality of reflective and refractive devices arranged to direct at least part of the light radiation from each of the at least two illumination sources to the surface such that at least part of the light radiation from each of the at least two illumination sources illuminates substantially the same area on the surface. The system also includes a sensor configured to receive light radiation from the at least two illumination sources reflected by the specimen and/or that pass by the specimen. The system also includes a power source configured to power the at least two illumination sources and the sensor.
