The Compact Tabletop (CT-10) utilizes Minus K's unique breakthrough technology to provide superior performance in a compact isolation platform measuring 2.7 inches tall, 12.6 inches deep, and wide. This unit, similar in height to Minus K's CT-2, provides comparable horizontal performance and extends payload range for smaller instruments.
This passive mechanical isolator performs 10–100 times better than a full-size air table. It accomplishes this without using air or electricity.
This vibration isolation platform is simple to use and features a unique 0.5 Hz vertical natural frequency and ~1.5 Hz horizontal natural frequency. With its trademark 0.5 Hz vertical natural frequency and about 1.5 Hz horizontal natural frequency, this vibration isolation platform is incredibly user-friendly. Just two modifications are needed. All kinds of benchtop microscopes work well with the CT-10.
With this performance, it is the thinnest, most portable, and easiest-to-use isolater ever made.

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