This instrument with combined ultra-high resolution (UHR) imaging and nano-probe microanalytical capabilities will strengthen and enhance ongoing and future research programs on semiconductors, (electro-optical materials), ceramics, intermetallics and superconductors at North Carolina State University at Raleigh. The microscope will operate at a maximum voltage of 200kV with point-to-point resolution of 0.18nm. An image acquisition system combined with appropriate digitizing and processing computer hardware/software will be interfaced directly with the high-resolution microscope. Further, this computer will be interfaced with the departmental VAX 11/750 to allow up and down loading of digitized experimental images for a detailed comparison with theoretically-calculated high resolution images.

该仪器结合了超高分辨率 (UHR) 成像和纳米探针微分析功能，将加强和加强北卡罗来纳州立大学罗利分校正在进行的和未来的半导体、（电光材料）、陶瓷、金属间化合物和超导体研究项目。 该显微镜的最大工作电压为 200kV，点对点分辨率为 0.18nm。 图像采集系统与适当的数字化和处理计算机硬件/软件相结合，将直接与高分辨率显微镜连接。 此外，该计算机将与部门 VAX 11/750 连接，允许上传和下载数字化实验图像，以便与理论计算的高分辨率图像进行详细比较。
