High-performance Vibration Isolation System

The Evolution of Vibration Isolation Systems

In July 1990, we developed the SHG high-performance Vibration Isolation System, the predecessor of the TDI Vibration Isolation System. We developed the TDI high-performance three-dimensional six-degree-of-freedom Vibration Isolation System based on this technology. The superior TDI isolates vibration from every direction because the horizontal and vertical isolation mechanisms are unified. Herz products are designed with our main goal, "supporting the Measuring Environment" in mind. With today's instruments rapidly increasing in precision and resolution requirements, the high performance TDI is the ideal table for the Nanotechnology Era.

Characteristics

Vibration Isolation mechanism

An air spring is the basic element of a Vibration Isolation System. Our original 'High Precision Air Spring' has been continually developed since Herz was established. The TDI achieves vibration isolation in all six degrees of freedom in three dimensional space by unifying the mechanisms for vertical isolation and horizontal isolation. Our vibration isolation systems have won the trust of consumers by delivering consistent results over many years.

Honeycomb bench / Plate

The honeycomb bench and plate should be chosen according to the instrument to be isolated. We developed the aluminum honeycomb bench to be lightweight and high stiffness. This honeycomb bench overcomes the load restrictions of floors and is widely popular. Herz classifies a honeycomb bench and plate as follows...
