Description
The laboratory is located on the 7th floor of the building and the external environment is rather complex. Multiple research rooms are placed side by side on the same floor, with a high density of people and goods coming and going. The distance from the elevator shaft to the SEM tube is only about 12 meters. Meanwhile, right beneath the building is a busy main road. There is a subway network beneath the main road, and there is a subway entrance directly beneath the laboratory building. These main vibration sources will conduct considerable vibrations to the tube of the electron microscope, affecting its ability to capture images normally.
The Supra55 integrates an air cushion inside, providing excellent shock absorption within the frequency range of 25Hz to 40Hz. The main purpose is to slow down the high-frequency mechanical vibrations generated inside the electron microscope, but it cannot eliminate the low-frequency vibrations from the ground.
The high-performance active vibration isolation system can perform active vibration reduction within the range of 0.7Hz to 200Hz, thereby providing a stable environment for the electron microscope and enhancing the quality of the captured images.
