Used LEO / ZEISS 440 #293640327 for sale

LEO / ZEISS 440 is a scanning electron microscope (SEM) designed and manufactured by the renowned optics and laboratory equipment maker, Carl LEO. The unit excels in the precise imaging and analysis of a variety of specimens in the areas of material sciences, microelectronics and life sciences. LEO 440 achieves a scanning resolution of up to 3.2 nm diameter and a magnification range of 1K to 1Mx using its powerful eddy-current corrected electrostatic lens. Its high-performance column makes possible a cathodoluminescence spectromicroscopy which is critical for several types of analysis, including point analysis, line scan analysis and hyperspectral imaging. The system features a low-vacuum field emission gun which reduces electron gun contamination that can lead to image drift over time, resulting in improved image quality for longer imaging times. Furthermore, the gun chamber is equipped with a condensator design which aids in the protection from cosmetic damage from the electron beam. ZEISS 440 enables electron beam lithography and sample patterning with a resolution of 5 nm with its focused gaussian gun. The sample chamber on the system is equipped with a low co-sputtering chamber that ensures a low evaporation pressure near the sample. The unit also provides sample preparation with a wide range of standardized and sample-specific preparation accessories including specimen holders, heaters and more. Its vacuum pumping system henckels minimizes dehydration and damage due to static electric fields. Overall, 440 is the ideal instrument for a variety of disciplines, including materials sciences, microelectronics and life sciences. Its superior resolution, impressive magnification range and numerous features make it a reliable and effective instrument for a variety of applications.
