ABSTRACT:
For carrying out several mutually complementary microscopic examinations, beams of different types or frequencies, for example light beams or acoustic beams, are focused simultaneously or successively on an object and recorded or visibly displayed in a known manner. The object is maintained stationary and is scanned in a grid pattern in two mutually perpendicular directions by at least one of the beams. A pillar arrangement is provided to receive different microscopic instruments which may be selectively pivoted by means of a rotary mounting plate into and out of a locked, exactly reproducible observation position. The instruments may be released for rotation out of the observation position independently of any vertical coarse-fine focusing displacement. Underneath a stationary object holder further microscopic instruments, such as an inverted optical microscope, may be mounted in such a manner that their height may be adjusted. In this fashion, simultaneous optical and acoustic microscope examinations of an object are possible, with the observations being effected from opposite sides of the object.
