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
