In the fields of precision measurement and high-end scientific research, the stability of instruments often directly determines the accuracy of data and the success or failure of experiments. Minute vibrations in the environment, especially low-frequency vibrations, are one of the main interference sources that affect the performance of precision instruments such as electron microscopes, optical profilometers, and photolithography equipment. Therefore, choosing a set of efficient and reliable active shock absorption tables has become a crucial step for many laboratories and industrial production lines to enhance the performance of instruments and ensure research results. Today, let's delve into how to choose a cost-effective active shock absorption table brand in scientific research and industrial applications.
Compared with the traditional passive shock absorption system,Active shock absorption tableBy detecting external vibrations in real time and dynamically generating reverse forces to counteract interference, its core advantage lies in its outstanding isolation capability against low-frequency vibrations (typically referring to 1Hz to 200Hz). Many precision instruments, such as scanning electron microscopes (SEM), transmission electron microscopes (TEM), atomic force microscopes (AFM), and white light interferometric profilometers, are extremely sensitive to extremely low-frequency vibrations below 1Hz. Passive systems are prone to resonance in this frequency band, which will instead amplify the vibration. However, active vibration isolation tables can fundamentally solve this problem and provide a pure and stable measurement environment.
The core technology lies in its advanced piezoelectric sensor and drive system. HERZ's active shock absorption table adopts an internal feedback loop, which can monitor the vibration of six spatial degrees of freedom (three translation axes and three rotation axes) in real time and actively generate counteracting forces, effectively suppressing the mechanical resonance of the system itself. Its operating frequency range can be as low as 0.5Hz (when paired with the LFS system), solving the problem of extremely low-frequency vibration noise.
AVI-200/400 series: A model of compact modular design. It is suitable for scenarios where existing equipment needs to be upgraded and renovated, such as providing low-frequency vibration isolation for desktop devices like optical profilometers, AFMs, and interferometers. Its modular design enables users to flexibly combine the instrument according to its weight and size, expand the load-bearing capacity, and is easy to install without the need for professional hoisting equipment.
AVI-600/UT-1000A series: Specifically designed for large and heavy instruments. For instance, the UT-1000A platform is a vibration isolation solution for electron microscopes, and its ultra-thin modular design can even support equipment weighing up to 3,500 kilograms. The maximum load-bearing capacity of this series of active shock absorbers can be expanded to 9,000 pounds by adding modules, and after installation, it hardly changes the overall contour of the microscope, achieving a perfect unity of performance and convenience.
