In the field of microscopy observation and optical manufacturing, vibration is one of the main interfering factors affecting equipment precision and data reliability. When external vibrations are transmitted to an optical platform, they cause slight relative displacement of lenses, resulting in blurred observation images, focus drift, and decreased processing precision. Especially in high-magnification microscopy and sub-wavelength optical component processing, even micron- or nanometer-level vibration disturbances can render an entire device inoperable.
To address this issue, installing rubber vibration isolators between the optical platform or equipment base and the ground is widely recognized as the most fundamental and effective vibration isolation measure. Rubber vibration isolators absorb vibration energy through elastic deformation while providing stable support, enabling optical equipment to quickly return to equilibrium when subjected to external disturbances.
Vibration isolation deployment for microscope equipment typically requires installing one rubber vibration isolator at each of the four corners or support points of the equipment base. Selection should comprehensively consider the microscope's total weight (including eyepieces, light sources, cameras, and other accessories), the main frequency components of the vibration environment, and the laboratory's specific requirements for vibration isolation performance.
For routine laboratory microscopes, using solid rubber vibration isolators with a vertical natural frequency of 6.5 to 12 Hz and a damping ratio of 0.05 to 0.2 can achieve ideal isolation effects. These isolators feature stable structure, equipped with leveling adjustment seats for precise leveling, and optional casters to accommodate laboratory layout adjustments.
For high-end equipment such as ultra-high magnification microscopes and confocal microscopes, where vibration control requirements are more stringent, hollow conical rubber vibration isolators with lower natural frequencies (4 to 8 Hz) and higher damping are recommended to achieve a wider isolation band and stronger resonance suppression capability.
The vibration requirements for optical manufacturing are often even more stringent than those for observation applications. In processes such as lithography, coating, and polishing, any vibration exceeding the allowable range can cause defects such as surface morphology deviations and uneven film thickness, resulting in serious economic losses.
The hollow conical rubber vibration isolator POT-G series is specifically designed for such high-demand scenarios. It adopts a combination of high-tech rubber and special structure, featuring large damping and short recovery cycles that effectively reduce resonance risk and ensure the stability of optical manufacturing processes. This series covers a load range of 50 to 700 kg, adapting to various needs from small optical experimental tables to medium-sized optical processing equipment.
Although rubber vibration isolators have the advantage of low maintenance costs, the following maintenance points should be noted during long-term use:
First, regularly check the installation status of the isolators to ensure bolts are tightened and leveling adjustment seats are not loose.
Second, observe whether the rubber body surface shows signs of cracking, deformation, or aging. While quality rubber vibration isolators typically have a service life of 5 to 10 years, aging may be accelerated in harsh environments with high temperatures or strong ultraviolet exposure.
Third, when adding or removing equipment accessories significantly changes the total weight, promptly evaluate whether the existing isolators' loads are still within the rated range, and replace with appropriate models if necessary.
