The scanning electron microscope provides microphotographs with up to five thousand times magnification. The generated images are images of the object surfaces and have a high depth of focus. Objects from micropaleontology such as foraminifera, ostracods and gastropods are routinely analyzed with the aid of this instrument. For this purpose a ZEISS SUPRATM 40 VP Ultra with a thermal field emission cathode (with variably adjustable pressure for detailed topographic imaging of non-conductive …
