AVI203S Series
Vertical & horizontal vibration isolation
High-load capacity with excellent stability

HOLMARC’s Passive Support - Automated Pressure & Level Controlled vibration isolation system that effectively isolates the optical table from vertical and horizontal vibrations throughout the critical 3 to 50 Hz frequency range, since most common large-amplitude sources of vibrations found in laboratories vibrate within this range of frequencies. If the source of compressed air is removed, the Optical Tabletop will lower until it securely rests on the supports and the table will no longer be isolated from floor vibrations.

Our AVI Series automated optical table supports can be used to significantly reduce the vibrations transmitted to an optical table setup in a noisy environment.
