Features |
 |
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. |
||
 |
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. |

 |
 |
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.
