User-Friendly Design: Ambient light operation. Multiple automated functions for alignment,
  focus and stigmation as standard features.

 

Screen Camera and Main Camera

Critical sample features can be easily identified in the viewing screen camera image on the LCD monitor while operating in ambient light.

 

 

 

Auto Drive Function for High-Speed Recall of Specific Area of Interest

 

All saved images are stored in an image database where the thumbnail of the image can be viewed.
Each thumbnail image contains the microscope settings used when the image was captured.
When the operator clicks on any thumbnail image and selects “auto drive”, the specimen stage is automatically driven to the position where the image was captured.

 

Image Navigation using Whole-View and Micro-Trace Function

The whole-view function allows a whole image of the grid to be acquired and displayed in the stage operation window. The micro-trace function stores and displays the movement path. This allows the operator to easily differentiate between examined and unexamined areas of the specimen.
Image navigation allows the storage of up to 100 stage coordinate positions and tilt angles. When a saved location is recalled, the instrument drives the specimen stage to the saved coordinate position and tilt angle.

 

 

Auto Pre-Irradiation, API

API is essential for imaging beam-sensitive specimens and for stabilizing specimens to prevent drift.
Operators can select from several modes, as shown below (Whole scan, Frame scan, and Area Scan), to optimize sample stabilization results.

 

 

 

By means of API, the contrast of examined areas (left) matches the surrounding embedded tissue and resin (right).

API effectively minimizes damage and specimen drift during observation.

 

Premium Image Quality: Fully Integrated camera and Newly Developed algorithm for Fully
  Automated serial image acquisition and Seamless Panoramic Imaging

 

Auto multiple frame function and Auto panoramic function capture and delineate seamless panoramic images for large format results.

 

● Continuous images can be collected, saved and stitched automatically.
● Images are automatically collected with high precision through the use of image shift or stage shift.
● Newly developed stitching algorithm combines automatically captured images into one panoramic view with the

   highest possible accuracy.

 

 

 

Outstanding Performance:Double-Gap Objective Lens

 

Double-Gap Objective lens design for HC and HR

 

● Hitachi’s unique Double-Gap Objective lens design can be used to generate a long focal length for High Contrast (HC)

   imaging or a short focal length for High Resolution (HR) imaging.

● With a simple software selection, the HT7700 operator can easily switch between High Contrast (HC) or High Resolution (HR)

   imaging mode based on sample requirement.

 

 

 

Advanced Applications: Optimized Hitachi 3D tomography, BF/DF STEM capability,

EDX microanalysis, EXALENS for superior high resolution imaging. Unique specimen

holders designed for advanced applications.

 

 

Electron Beam Tomography (optional)

 

The highly stable Hyper stage of the HT7700 with ±70° automated tilt capability, coupled with Hitachi’s unique reconstruction algorithms . including Topography Based Reconstruction (TBR)-can be used to create high quality tomographic reconstructions.

 

Double-Axis Tomography (optional)

 

The combination of double-axis tomography and Hitachi’s unique reconstruction software can be used to achieve 3D reconstructions with fewer artifacts and more accurate results.

 

Scanning Transmission Electron Microscope (STEM) (optional)

 

Both Bright Field (BF) and Dark Field (DF) detectors can be added to the HT7700 for STEM analysis.
BF-STEM provides better contrast and image sharpness due to reduced chromatic aberration.
Furthermore, scattered electrons are detected with high sensitivity by means of DF-STEM, resulting in better contrast for low-Z specimens.
When an EDX detector is included, multiple elemental maps can be recorded simultaneously.

 

High Resolution Lens EXALENS (optional)

 

EXALENS is a newly designed objective lens for the HT7700.
By achieving a smaller spherical aberration coefficient (Cs), a resolution of 0.144 nm (lattice, accelerating voltage : 120 kV) is obtained.
EXALENS excels at high resolution imaging at lower accelerating voltage, facilitating analyses of soft materials, carbon-based nanomaterials and polymers.

 

Specimen Holders for a Variety of Advanced Applications (optional)

 

In addition to various Hitachi holders (below), specialty holders for low temperature, heating, in-situ and other experiments are available from several manufacturers.

 

● One Touch Single Tilt Holder
● Double Tilt Holder
● One Touch Three Specimen Holder
● Powder Heating Holder
● Rotation Holder
● Three Specimen Holder
● X-ray Analysis Holder

 

 

Environmentally Friendly:Eco Product

 

● The turbomolecular pump is a key component of the HT7700 vacuum system. It facilitates a cleaner column and reduction

    in power consumption of 30% (operational mode) and 70% (static mode) compared to the previous model,

    the H-7650 TEM (2010).

● HT7700 is an environmentally-friendly “Eco Product” designated by Hitachi Ltd.
