Vibration isolation platform adapts to space constraints

The new CT-10 passive isolator from Minus K Technology is the industry’s thinnest vibration isolation platform, making it ideal for applications in microscopy, metrology and photonics systems. With a footprint of 320 x 320 mm and a height of just 68 mm, the CT-10 platform is also capable of isolating vibrations down below 1 Hz.

The completely passive unit exploits a series of mechanical isolators to deliver a vertical natural frequency of 0.5 Hz, and around 1.5 Hz for horizontal natural frequencies – considerably better than can be achieved with air tables or active systems. “Vibration isolators for small microscopes, especially AFM, have typically been much larger than needed,” said Erik Runge, the company’s vice-president for engineering.  “The CT-10 offers the signature 0.5 Hz vertical performance we have become known for, but in a much smaller package.”

<a data-fancybox data-src="https://platoaistream.com/wp-content/uploads/2024/01/photonics-west-lights-up-san-francisco-physics-world-2.jpg" data-caption="Better isolation The new CT-10 vibration isolator from Minus K Technology offers a more compact solution for microscopy applications.

The CT-10 platform achieves a high level of isolation in multiple directions, and also offers the flexibility to tailor the vertical resonant frequency to meet the needs of the application. When adjusted to a vertical natural frequency of 0.5 Hz, the platform achieves an isolation efficiency of around 93% at 2 Hz, 99% at 5 Hz, and 99.7% at 10 Hz.

The passive design does not require electrical power or compressed air. There are no motors, pumps or chambers, and no need for regular maintenance. The tabletop solution can also be easily moved between locations for extra flexibility.
