Utilizing Minus K’s unique breakthrough technology, the Compact Tabletop (CT-2) offers the finest performance in a 2.7-inch-tall isolation platform. Better horizontal performance and more payload ranges for larger instruments are features of this machine, which is an improvement over Minus K’s CT-1.
This fully passive mechanical isolator performs 10–100 times better than a full-size air table. It accomplishes this without using energy or air.
This vibration isolation platform is simple to operate and features the trademark 0.5 Hz vertical natural frequency and ~1.5 Hz horizontal natural frequency. There are only two adjustments. The CT-2 is suitable for any type of benchtop microscope.
When providing this performance, this is the thinnest, most portable, and easiest-to-use isolator available.
The CT-2’s vertical 1/2 Hz performance is seen by the vertical curve below. Compared to standard air tables, the CT-2 provides natural frequencies as low as 1.5 Hz horizontally.

Performance |
- Horizontal frequencies are weight-dependent.
- Horizontal frequency of ~1.5 Hz is achieved at or near the upper limits of the payload range.
- The horizontal frequency will increase at the lower payload weights.
- Vertical frequency is tunable to 0.5 Hz throughout the payload range.
