In the field of nanoscale measurement and high-end manufacturing, environmental vibration is a "hidden killer" of resolution and stability. Whether it is scanning electron microscopy (SEM), atomic force microscopy (AFM), or optical profilometer, a stable and undisturbed working environment is required. At this point, a suitable microscope specific shock absorber becomes particularly important. So, as a user, how to follow the crowdShock absorber manufacturerWhich one is suitable for your device?
This article provides a detailed analysis of the core indicators of ultra stable seismic isolation technology and introduces the mature seismic reduction solutions provided by Younikon Technology Co., Ltd. (Yiying Technology).
Many laboratory personnel have found that when instruments are placed on high-rise buildings or near highways or computer rooms, the images may exhibit stripe jumping and poor repeatability of measurement data. This is because there is a broadband micro vibration of 0.5-200Hz on the building floor, while ordinary rubber pads or passive floating platforms are almost ineffective against low-frequency vibrations (<5Hz).
The core function of the microscope specific shock absorber is to actively isolate these low-frequency disturbances. For example, HERZ's AVI series, a manufacturer of shock absorbers, uses piezoelectric sensors and drivers to actively detect input vibrations and generate reverse forces for dynamic elimination, achieving six degrees of freedom full space vibration isolation.
When choosing a shock absorber manufacturer, the first step is to distinguish between active and passive products:
| comparative dimension | Passive shock absorber platform | Active shock absorber platform |
|---|---|---|
| Vibration isolation principle | Springs, air cushions, etc. absorb energy | Electronic feedback generates a reverse force |
| Effective frequency | Usually>5-10Hz | Active 1-200Hz, passive>200Hz |
| Low frequency performance | Poor, may cause resonance amplification | Good, no low-frequency resonance |
| Typical Applications | Ordinary optical microscope, balance | AFM、SEM、 Interferometer, lithography equipment |
For microscope specific shock absorbers, it is recommended to prioritize active models. For example, the HERZ AVI-200 WORKSTATION has an active isolation range of 1-200Hz, a response time of only 5-20 milliseconds, and does not require a gas source or setup time, making installation simple.
As a professional manufacturer of shock absorbers, the quality of their products can be judged by the following data:
Isolation range and transmission rate:
An excellent active damping platform should cover 1-200Hz. For example, the HERZ AVI-600 has a transmission rate below -35dB (i.e. vibration attenuation below 1.8% of the original intensity) when exceeding 10Hz.
Passive mode should cover high frequencies above 200Hz.
System noise and recovery time:
The system noise should be below 50nG/√ Hz to avoid introducing additional vibrations.
The recovery time should be less than 10-20 milliseconds and respond quickly to external shocks.
Load bearing and expandability:
Desktop all-in-one models (such as TS series) are suitable for small and medium-sized devices such as profilometers and AFM.
Modular bases (such as AVI-600) support large equipment, with considerable load-bearing capacity per module. They can be expanded to 9000 pounds by adding modules and are suitable for SEM, TEM, and other applications.
Atomic Force Microscopy (AFM) or Optical Proformer: HERZ TS series active shock absorber is recommended. It provides six degrees of freedom three-axis active vibration isolation, with LCD display for real-time XYZ direction vibration and horizontal automatic adjustment function, which can maintain stability even if the load center of gravity deviates.
Scanning/Transmission Electron Microscopy (SEM/TEM): HERZ UT-1000A active damping system is recommended. This product is customized and integrated for large electron microscopes, with active vibration isolation starting from 0.5Hz. It adopts an ultra-thin modular design and can be installed without the need for specialized lifting equipment. For example, a 3500 kilogram FEI Titan TEM can be stably supported by four UT-1000A modules, effectively eliminating low-frequency vibration noise.
Photolithography equipment or high-precision metrology equipment: The AVI-600 series can be selected, with its compact modular design suitable for a variety of large instruments.
As a partner of multiple international shock absorber manufacturers, Unicon Technology Co., Ltd. (Yiying Technology) can provide customized seismic isolation solutions based on different equipment weights, sizes, and on-site environments.
A professional shock absorber manufacturer should not only provide hardware, but also include:
On site investigation: Conduct on-site measurement of environmental vibration spectra and select targeted models.
Installation and debugging: For example, UT-1000A only requires leveling the device and raising the feet by 5 inches to place the module, without the need for lifting.
After sales service: Provides 7x24 hour online support and 8-hour quick response.
Choosing a microscope specific shock absorber stage means choosing the authenticity of data and the long-term value of the instrument. The technical level of the shock absorber manufacturer directly determines whether your expensive equipment can perform as expected.
From AFM to TEM, from profilometer to lithography machine, a suitable microscope specific shock absorber is the "foundation" for laboratory precision measurement. Unicon Technology Co., Ltd. (Yiying Technology) collaborates with brands such as HERZ to provide you with ultra stable seismic isolation solutions from desktop to heavy-duty equipment, effectively reducing environmental interference and unleashing instrument potential.
