ＡSupporting the Measuring Environment

Into the Nanotech Era・・・・
DT Desktop Vibration Isolation System
Herz has developed the new DT vibration isolation system over the past twenty years with the challenges ofnanotechnology research in mind. The measuring environment of the nanotechnology era presents new challenges
that require the latest in vibration isolation and vibration control. In response to this, Herz has improved on thevertical isolation provided by the air spring system of the original DT system by developing a 360 degree horizontal
isolation mechanism to produce the 3D/DT. After conducting modal analysis on the new damping feet andcompliance tests on the mounting plate, we have changed the design of the DT to offer the most reliable desktop
vibration isolation solution for the Nanotechnology Era.

WithoutIsolation

3D/DT-A Desktop Vibration Isolation SystemDT-ADesktop Vibration Isolation System
The 3D/DT-A and the DT-A systems use an external air supply (aircompressor, air supply, or nitrogen tank). The DT’s air regulator ensuresthat the air pressure will be perfectly suited to the instrument that is being
isolated. The three auto-leveling sensors maintain the system’s level.
The 3D/DT-A features a damping mechanism that provides 360 degree
horizontal isolation, high damping finish on the frame and mounting
plate, and ultra-rigid damping feet. The 3D/DT-A is the ideal vibration
isolation solution for the Nanotechnology Era.

3D/DT Top Plate Damping Treatment
The progress of nano-level science and technology is relentless. So Herz develops v bration isolation technology continually. In
order to meet the needs of the next generation of instruments and applications, Herz has developed its newest series, the 3D/DT,
featuring high-damping technology and the ultra-high performance three-dimensional air spring.

3D/DT-6050M-E Tapped Mounting Plate

DT-M comes standard with a manual hand pump. After the instrument is loaded on the system, use the pump and three air valves to supply
the correct amount of air to make the table float evenly. There is no need for an external air supply so you can easily achieve a vibration-freeenvironment. The 3D/DT-M comes standard with a high-damping finish on the frame and mounting plate that make it a simple, easy-to-use
solution for the Nanotechnology Era.

１０１００The desktop system with the horizontal
isolation mechanism ［3D/DT］
effectively isolates in three dimensions.
The horizontal resonance is at 1.0 –2.0 Hz. The simple design provides
unprecedented levels of isolation
performance. Most buildings have floor
vibrations in the few Hz – 50 Hz range.
The 3D/DT provides great isolation
performance in this range.
