Used ZEISS 902 #9030859 for sale

ZEISS 902 is a scanning electron microscope (SEM) which is used to image the structure and composition of a sample at a very high magnification. It is capable of producing highly detailed, three-dimensional images of the sample's surface. It does this using electron optics to project a focused beam of electrons onto the surface of the sample. 902 is a field-emission scanning electron microscope that utilizes an inverted column design which enables a wide range of specimen measurements. It is a thermionic SEM that uses conventional thermo-electron emission for its electron source. The sample is held between a pair of electromagnetic lenses, which act as a focuser and a scanner to deflect the electron beam. ZEISS 902 is equipped with several detection instruments, including a backscattered electrons (BSE) detector. This detector is sensitive to the atomic number of the sample material, meaning it can generate contrast between different chemical elements in the sample. 902 is also able to generate secondary electrons (SE), and a high-angle annular detector system (HAADF) that generate an image with bright spots and dark background. Another type of detector that ZEISS 902 can utilize is the electron-beam induced current (EBIC) detector, which is used to detect local differences in the surface topography. This is useful for generating topography or depth maps in order to study three-dimensional structures. 902 also features a wide range of adjustable parameters and automated routines which make the instrument suitable for a wide range of applications. ZEISS 902 is a versatile microscopy tool which is suitable for use in fields such as materials science, forensics, and life sciences. It is capable of imaging samples at a microscopic level using a range of techniques, making it a useful tool for both research and industrial applications. 902 is a reliable, high-performance scanning electron microscope which provides excellent quality images at an affordable price.
