HT7700 Microscope
Aug 2010

MAIDENHEAD, England, Aug. 17, 2010 — The HT7700 120-kV transmission electron microscope from Hitachi High-Technologies Corp. features 100% integration of all functions into the graphical user interface. Optimized for high-contrast imaging at low electron doses, it is designed for biomedical research and research and development for pharmaceutical, advanced materials, nanotechnology and soft carbon-based materials.

The microscope features a high-sensitivity real-time digital CCD camera that enables all operations to be performed through the graphical user interface, including setup, alignment, image adjustment and image acquisition. Practical operation is performed on a console separate from the electron column, similar to scanning electron microscopy, reducing the installation space required and making the instrument easier and more intuitive to use by ensuring that all functions are available in one location.

The company says that the integrated real-time camera provides higher sensitivity than a traditional fluorescent screen, so live high-contrast imaging is performed easily in a fully lit room, and traditionally challenging low-contrast specimens can be easily observed. Beam-sensitive specimens can be more easily observed than with previous generation instruments which required higher illumination levels. LCD screen observation enables simplified operation and observation in normal room light. The standard high-sensitivity real-time camera can also be supplemented with a choice of higher resolution CCDs that are also fully integrated into the HT7700 user interface.

Enhanced digital imaging capabilities include the company’s EMIP-SP electron microscope image integration software for image archiving, classification and video acquisition, as well as fully integrated optional dual-axis auto-tilt series acquisition and optional EMIP-3D three-dimensional reconstruction software.

The turbo molecular pumping system is part of the eco-friendly design. It ensures a clean vacuum environment and low contamination rates and results in low power consumption.

Standard functions include image shift/stage shift and video recording.

An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
