Zeiss Supra 55VP FEG SEM

Zeiss Supra 55VP FEG SEM

The Supra 55VP is a high resolution scanning electron microscope (SEM) that uses a Schottky-type field-emission electron source. A beam booster is used to optimise electron optical performance at all accelerating voltages. In addition, the optical column has no crossovers and utilises a magnetic/electrostatic objective lens to minimise beam imperfections at low voltage by reducing chromatic aberration. This instrument can also be operated in Variable Pressure Mode, up to a pressure of 133Pa, thus providing charge compensation for materials with little or no conductivity.
