Used OMICRON UHV Gemini #9058734 for sale

OMICRON UHV Gemini is a scanning electron microscope capable of producing high-resolution images of a wide range of samples, from highly sensitive biomedical samples to hard, brittle materials. The microscope operates in ultra-high vacuum conditions, providing a more stable and pollutant-free imaging environment than open-air microscopy. The equipment uses electron optics, field emission and energy detectors, and an optical column design to accurately identify and image sample characteristics. The microscope has a large rectangular chamber that houses the optical column and sample staging system. An ultra-high vacuum pump maintains the chamber's vacuum pressure, allowing electrons to travel down the optical column at high speeds and accurately image the sample. A gun turret containing multiple electron guns allows the user to choose from a range of working and collection voltages, depending on the sample characteristics. The gun and detection unit also permit the user to perform low voltage imaging. The user can adjust the stage to produce a field of view between 0.5 and 1200 nm, allowing for high resolution imaging of small features. The stage also includes a tilt mechanism, allowing the user to tilt the sample to optimize imaging angles. Sample imaging is further enhanced by the machine's chromatic aberration and spherical aberration correction capabilities. UHV Gemini also includes a range of imaging modes, allowing the user to observe the sample's topography, geometrical and mechanical properties. For instance, secondary electron imaging mode allows for contrast across the sample's surface, while electrical mode permits for detection of electric field effects in the image. Other imaging capabilities include backscattered electron imaging, X-Ray Parallel Beam imaging, Cathodoluminescence, and Cryo-SEM imaging. In combination, these imaging resources provide the user with the ability to accurately and reliably examine and discern a range of information from the sample. OMICRON UHV Gemini is a powerful and versatile scanning electron microscope that helps advance study in a variety of fields, from semiconductor design to materials research.
