Matters needing attention in the use of Hitachi desktop scanning electron microscope TM4000

An optical camera can be installed in the sample bin to take pictures,

In the past, the target position was found through experience, but now it can be operated directly on the display screen. When shooting SEM images, because TM4000 and TM4000Plus are equipped with two-axis motors, the operation that originally needed manual adjustment only needs to select the position to be observed on the display.

Finding target position: refers to the operation of confirming the position of the sample being observed and finding the position of the sample to be observed. In general, the magnification of the electron microscope is high, and it is necessary to observe not only the local image but also the whole image.

*2 Double-axis motor table: a device that can automatically move the sample to the SEM image shooting position according to the observation requirements of the operator.

When confirming the photographed SEM images, it takes some time to find the observation positions of all SEM images due to the high magnification of SEM images. The model can use software to correlate the position relationship between low-power and high-power SEM images and display the results on the display, which makes the position of each image more intuitive.
