H7650 TEM

The Model H-7650 electron microscope
has been designed so that a wide field of view is obtainable in the low and medium magnification range frequently used for research in medical science and biology, and for research and development of pharmaceuticals, polymer materials, etc. and that biological specimen can be observed with a high contrast. Accelerating voltage is 120 kV at maximum. Focal distance is selectively usable between high-resolution and high-contrast applications by means of a double-gap objective lens. Both TEM main unit and standard-equipped digital camera system are integrally controllable by one personal computer (PC). On the liquid crystal display (LCD), magnification and other imaging conditions are displayable and settable. In addition, TEM images shot with the digital camera can be displayed on the same LCD. The auto focus and auto stigma functions characteristic of the Model H-7600 are incorporated as standard. Since the mounted digital camera is capable of displaying max. 18 frames per second, focus adjustment and astigmatism correction can be carried out while watching the LCD and a checked image can be saved as it is. Thanks to a high sensitivity of the camera, image observation can be started from an electron beam dose as low as 10-12 C/cm2 order where nothing can be seen on the fluorescent screen.
Therefore, specimen damage due to electron beam irradiation can be minimized.
System configuration is selectable according to application including the evacuation system
