Features

Active Isolation Technology Enables Super Low Frequency Isolation

The Guardian workstation includes two active isolation modules each contains 3 sensors and 3 actuators to actively sense and compensate for vibration in six degree of freedom real-time. It not only removes the resonance response inherent to the passive system, but provides up to 34 dB (50 times) additional isolation.  Isolation starts at 0.5 Hz and reaches 20 dB (10 times) at 1.5 Hz. It vastly outperforms not only the passive spring-based systems, but also the best pneumatic workstations.

Robust Passive Isolation with Easy Leveling Mechanism

One special feature about Guardian technology is that it combines the powerful active modules with Newport's patented VIBe™ passive mechanical isolator design to achieve the best performance across a wide frequency range. The improved constant natural frequnecy VIBe isolators starts passive isolation from 8 Hz and provides a solid and quiet foundation for the active modules to further reduce the vibration amplitudes below 50 Hz. The carefully designed leveling mechanism in the modules allow users to easily level their system prior to use.

Powerful Control Capability

The Guardian™ Controller features multiple essential functions on the front panel, as well as real time control display for six axes. A full set of control functions are available using software suite provided with the product to achieve even more precise vibration control or 24/7 vibration data monitoring and recording. The sub-hertz, ultra-low noise electronics and advanced DSP control system inside the controller provides the most accurate vibration compensation for sensitive applications.

Maximized Precision with Modal Damped Tabletop

In addition to active and passive vibration isolation, a well damped working surface reduces resonances from top down, which helps tremendously for any high precision applications. Guardian™ workstation embraces modal damping, another world innovation for the most critical applications. Precision Grade optical breadboard serves as tabletop for Guardian™ workstation, bringing damping performance to the next level. The patented modal dampers are installed along the entire perimeter of the tabletop, providing effective and broadband damping for your delicate instruments.

Superior Rigidity with Integrated Frame

The Guardian™ workstation delivers superior rigidity with its all-in-one design. Carefully designed to provide the maximum mechanical stability, the fully welded frame system firmly supports the active modules as well as the tabletop. It also provides ergonomic workstation environment for the users to perform their applications.

Effortless Installation and Maintenance

Guardian workstation features specially designed packaging that allows users to simply roll their system off into the lab. Every component including tabletop are pre-installed on the frame.

Guardian Typical Settling Time

Guardian can reduce the platform’s reaction to the disturbances acting directly on the platform, whereas passive systems and some active systems can reduce only the vibration coming from the floor through the isolators. This is illustrated by the test results in the graph. The graphs represent the time histories of acceleration caused by a short (about 0.01 s) triangular pulse with maximum force about 1.5 lbs. created by an instrumented hammer near the corner of the breadboard (6 in. from edges) and measured by the accelerometer placed nearby. The settling time after this disturbance is negligible with active controls, whereas it can be of the order of seconds with passive isolation acting alone.

Versatile Frame Allows Easy Accessory Mounting

Optional hip guard and other accessories could be added to Guardian workstations using various mounting locations on the frame.
