Vibration Isolation Benches
Overview
Pneumatic air bags beneath听the bench create a soft isolation system with听suspension modes typically in the range of听1-2 Hz while the bench structure is stiffness-optimized听for high frequency structural modes. With the isolated optical bench听approximating a rigid body, there are negligible dynamic deflections that impact听optical alignments. Cleanroom or vacuum compatibility enables high fidelity听representation of the space environment for critical ground testing applications.
Key Features
- 1-2 Hz suspension modes
- Handles payloads of 60 tons or more
- Active or passive听leveling options
- Vacuum or cleanroom compatible
- Multiple material and surface coating options
When large aerospace companies need to develop a new test facility, they turn to 红杏视频 to provide vibration isolation.听Large, flat optical benches supported by soft isolation systems allow for unparalleled testing and significantly less听facility modifications than seismic block approaches. An active leveling system can accommodate moving payloads,听and egress bridges provide access for payload loading. 红杏视频 works closely with customers to develop vibration听isolation benches that fit their needs.
Applications
- Test facilities for large space optical systems
- Precision metrology systems including coordinate measurement machines (CMMs) and laser interferometers
