Overview   Laser-Optic measurement is a delicate process requiring consistency, precision, and isolation from vibration. The measurement requires to stay in a precise and consistent position of optical parts while isolating floor vibration. This calls for the optical breadboard’s optimal dynamic stiffness and effective reduction of vibration from the system itself.

Isolating vibration input in a low-frequency range below 10Hz, VAIS-PT will provide an Optic-Laser test's optimal, stable vibration environment.

1. Pneumatic Support Frame

The pneumatic support frame further strengthens VAIS-PT’s robustness against aperiodic impulse vibration.

2. Floor Feed-Forward Control

Utilizing feedback and floor feed-forward controls, VAIS-PT has an excellent capability to prevent low-frequency vibration disturbance induced by the structural resonance of the building.

3. LED Status Indicator

Three LED lights (Red, Green, Blue) on the front panel conveniently display the status on vibration environment changes and serviceability.

4. Digital Control System

The digital controller provides a convenient user interface, setup parameter modification, and system diagnosis.

5. Remote Support

AMTEK provides a remote real-time support for convenient performance diagnosis and technical support.

1. Application note

(1) Precise and consistent locations of optical parts on optical breadboard top are critical for Laser-Optical experiments. However, there seldom has been much interest in anti-vibration system considering vibration input’s amplitude and characteristics.

(2) Optical breadboard support frame selection is crucially essential for the composition and precision of the Laser-Optic experiments. Pneumatic passive isolation systems aren’t as effective on isolating low-frequency vibrations as on high-frequency ones.

(3) VAIS-PT is exclusively developed for Laser-Optic experiments. The optical breadboard is designed with stiffness, flatness, and repeatability in mind and the pneumatic active isolation system completely isolates vibration of all frequencies.
