BM-8 Specification Sheet

The BM-8 bench top platform offers 10-100 times better performance than a full size air table in a package only 4.6 inches tall, and without air or electricity!

This vibration isolation platform is extremely easy to use and offers extreme performance. It offers a 1.5 Hz or lower horizontal natural frequency and our signature 0.5 Hz vertical natural frequency. There are only two adjustments.

They can also be made cleanroom and vacuum compatible.

See a typical performance curve in the specification sheet.

Performance
  • Horizontal frequencies are weight dependent.
  • Horizontal frequency of 1.5 Hz (or lower) is achieved at the upper limit of the payload range.
  • At the lower limits of the payload range the horizontal frequency is approximately 2.5 Hz.
  • Vertical frequency is tunable to 0.5 Hz throughout the payload range.
