  • Scanning scattering microscope with hemispherical mirror and microfocused beam
    Patent number: 4954722
    Abstract: A method and apparatus (10) for producing two-dimensional micrographs of overall surface microtopography of a given specimen (19) by using a photodetector (22) to measure the off-specularly reflected light from a focussed light beam (50) which is projected through a hemispherical mirror (20) onto the specimen surface as the specimen surface is scanned by the focused beam of light (50). Scanning can be accomplished either by moving the specimen surface (19) as a result of moving the sample holding member (18) or by moving the focused beam of light by means of a light beam deflection device (25).
