Condition: excellent (used), ZEISS Type: DSM 962 The digitized scanning electron microscope DSM 962 is a device equipped with an integrated 4 MB image memory, a 40 MB hard drive for internal image storage, as well as drives for external storage of data and images. This allows for quick and easy acquisition of information about the composition and morphology of specimen surfaces, even down to the sub-micrometer range. With a magnification range of 5x to 300,000x, both the examination of macrostructures and microstructures is possible. Through special attachments, the range of applications can be significantly expanded, enabling, for example, analytical investigations in micro-areas of the surface. The device can be operated using conventional switches or via the keyboard and mouse (optional). The electron optics and vacuum control are conventional. The functions of the image memory are operated using the keyboard or mouse (optional). A separate information display is located centrally on the control panel for displaying the menus. This user manual is intended to serve as a guide for the user to achieve the best possible results with the device. The explanations have been kept as simple as possible in order to provide even a less experienced user with the necessary knowledge.
