Environmental vibration is an important factor affecting measurement accuracy and imaging quality in scientific research scenarios such as semiconductor testing, material characterization, and precision optical measurement. Whether it is personnel movement, equipment operation, or external environmental disturbances, micro level vibrations may occur, interfering with the normal operation of precision instruments such as scanning electron microscopes, profilometers, and probe stations.
Shock absorber performanceBecoming a key configuration to ensure the stability of experimental data and improve measurement repeatability is also an indispensable aspect of laboratory environment optimization.
Younikon Technology has long served scientific research institutions and high-tech enterprises, accumulating mature application experience in the fields of precision measurement and environmental vibration isolation. It has launched an active damping solution suitable for scientific research scenarios for high-precision instruments, providing support for nanoscale measurements with stable damping table performance.
1、 Core requirements for shock absorber performance in scientific research scenarios
There are strict standards for vibration control in scientific research experiments, and ordinary passive vibration isolation equipment is difficult to meet the low-frequency suppression requirements, especially in the vibration frequency range of 1-200Hz, which can easily cause imaging blur and data drift. The research grade shock absorber platform must meet the following conditions:
Can cover low-frequency isolation and reduce the impact of environmental disturbances;
Capable of rapid response and real-time cancellation of vibration signals;
Support multi-directional vibration isolation, balancing stability in both vertical and horizontal dimensions;
Modular design, adaptable to different loads and installation scenarios;
Stable operation, low noise, low power consumption, and no interference with instrument measurements.
The above indicators collectively determine whether the performance of the shock absorber can match the requirements of scientific research equipment, and are also the core considerations for users when selecting.
2、 How can active compensation technology improve the performance of shock absorbers
The research grade shock absorber provided by Younikon adopts active vibration isolation technology, which detects vibration signals in real time through piezoelectric sensors and generates reverse force for dynamic compensation by the control system, suppressing micro level vibrations from the source and significantly improving the performance of the shock absorber.
Its working principle is: the shock absorber platform is equipped with a built-in piezoelectric sensor to collect XYZ three-axis vibration data, convert mechanical signals into electrical signals, and the controller quickly calculates and drives the actuator to generate equal and opposite force to counteract the incoming vibration. The internal feedback loop can reduce mechanical resonance, avoid secondary disturbances, and achieve stable isolation effect.
This technology has stable performance in terms of parameters: the HERZ AVI full series active isolation range covers 1Hz-200Hz, and the UT-1000A platform with LFS system can extend down to 0.5Hz; the response time is only 5-20 milliseconds, which can quickly and stably vibrate; The system noise is below 50nG/√ Hz and will not cause additional interference to precision measurements; Supporting six degrees of freedom vibration isolation, balancing vertical and horizontal stability, and comprehensively improving the performance of the shock absorber platform. The HERZ AVI-400 series is superior to any passive system, with no low-frequency resonance, vibration recovery time less than 10 milliseconds, and no need for calibration or pressure support.
3、 Application of research grade shock absorber performance in practical scenarios
The active shock absorber platform of Younikon has been widely used in equipment such as scanning electron microscopes, transmission electron microscopes, optical profilometers, probe microscopes, etc. It operates stably in university laboratories, enterprise research and development centers, and testing institutions.
In electron microscopy applications, the HERZ UT-1000A platform is an industry recognized ideal solution that supports scanning electron microscopy (SEM) and transmission electron microscopy (TEM), including the FEI Titan TEM weighing up to 3500 kilograms. Before installing the shock absorber, high magnification imaging is susceptible to vibration and the image clarity is insufficient; After being equipped with an active damping platform, micrometer level vibrations are effectively suppressed, and the imaging quality and resolution are significantly improved, enabling stable high-power observation and material analysis.
In contour and optical measurement scenarios, stable damping performance can reduce measurement errors in parameters such as step height and surface roughness, and improve data consistency and repeatability. The TS series is a desktop all-in-one design designed specifically for small devices such as profilometers and microscopes. It provides active isolation in the range of 0.7-100Hz with 6 degrees of freedom and 3 axes, and is equipped with an LCD display panel to display real-time vibrations from XYZ directions.
The shock absorber platform adopts a modular structure, and the number of modules can be adjusted according to the load. The AVI-200 series is suitable for small and medium-sized instruments, while the AVI-600 series can bear up to 9000 pounds, meeting the load-bearing requirements of different instruments; The installation process is simple, there is no need for complex debugging, and it is quickly put into use; Low power design (AVI-200 only 9W, AVI-600 standard 27W) ensures continuous and stable operation, suitable for long-term use in scientific research sites, and continuously guarantees stable performance of the shock absorber platform.
