Features
Simultaneously providing high resolution and high contrast over large fields of view
Hitachi's proprietary dual-mode objective lens enables various lens modes for a wide variety of observations. Low magnification provides easy navigation across the entire grid, High-Contrast (HC) observation allows increased contrast over a large field of view, and High-Resolution (HR) observation reduces the focal length for enhanced resolution.
High-contrast observation
Specimen：Rat kidney
Accelerating voltage：80 kV, Magnification：x300
High-resolution observation
Specimen：Asbestos (Crocidolite)
Accelerating voltage：120 kV, Magnification：x400,000
Comfortable operating and remote operation in a broad range of scenarios
The HT7800 series offers a fully integrated workflow in one intuitive guided user interface. Both image navigation, using the wide field-of-view screen camera, and image acquisition, using the high-resolution camera, are carried out in one software platform. Digitalized operations also benefit remote applications, some of which include simultaneously sharing and exchanging captured TEM images at multiple points.
High-sensitivity screen camera allows intuitive operation
Automation capabilities supporting consistent TEM operation
Combining an intuitive workflow with sophisticated automation capabilities allows users of any experience level to achieve high-throughput, high-quality data acquisition. The system features enhanced automation capabilities, including automatic beam alignments to support routine alignment tasks, Image Navigation for automated and efficient image acquisition, and EM Flow Creator＊1 for flexible workflow configuration.
