Hitachi's proprietary dual-mode objective lens provides versatility by supporting a wide variety of applications. Perform two different lens actions to achieve both High Contrast (HC) and High Resolution (HR) imaging capabilities with a single click. Low magnification provides easy navigation across the entire grid, High Contrast (HC) observation allows increased contrast over a large field of view for life science capabilities, and High Resolution (HR) observation reduces the focal length for enhanced resolution for materials science capabilities. The HT7800 series is the only system in the industry to offer both high-contrast and high-resolution expandability without compromise.
High-contrast observation
Specimen: Rat kidney
Accelerating voltage: 80 kV; Magnification: x300
High-resolution observation
Specimen: Asbestos (Crocidolite)

The HT7800 series offers an ergonomic workstation for 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.
