日立 HITACHI S-6100 扫描电子显微镜用途：广泛应用于材料科学、半导体、生物学、地质学等领域，可对样品微观形貌进行观察，也能辅助分析样品结构与成分。技术原理：电子枪发射电子束，经电磁透镜聚焦、加速后轰击样品表面。电子与样品相互作用，产生二次电子、背散射电子等信号，探测器收集这些信号，并将其转化为图像，以此呈现样品微观特征。性能：分辨率可达 4nm（加速电压 15kV，二次电子像）；放大倍数范围在 20 - 60 万倍；加速电压 0.5 - 30kV；样品室可容纳一定尺寸样品，满足多样品操作需求 。Product Name: Hitachi HITACHI S-6100 Scanning Electron MicroscopePurpose: Widely used in fields such as materials science, semiconductors, biology, and geology. It can observe the micro - morphology of samples and assist in analyzing the structure and composition of samples.Technical Principle: The electron gun emits an electron beam, which is focused and accelerated by electromagnetic lenses and then bombards the sample surface. Electrons interact with the sample to generate signals such as secondary electrons and backscattered electrons. Detectors collect these signals and convert them into images to present the micro - characteristics of the sample.Performance: The resolution can reach 4nm (secondary electron image at an acceleration voltage of 15kV); the magnification range is 20 - 600,000 times; the acceleration voltage is 0.5 - 30kV; the sample chamber can accommodate samples of a certain size to meet the needs of multi - sample operations.
