Accurion Benchtop Vibration Isolation Systems

State-of-the-art compact active vibration isolation systems from Accurion   

Halcyonics Benchtop Units: i4 & Nano   

Accurion designs and manufactures advanced vibration reduction systems for today's exacting nanotechnologies. Whether it's high-resolution measurement or a high-precision manufacturing process, effective anti-vibration solutions are required to achieve maximum performance.

Active vibration isolation overcomes the limits of passive damping systems, enabling the attenuation of vibrations caused by machinery, people, traffic, even sound waves, that would disturb delicate instruments.

The systems detailed below are designed for small to medium sized applications light enough to sit on a typical table or benchtop.

i4 Series

Applications

• Scanning probe microscopy: AFM, SNOM, STM, etc
• Inverse microscopy
• Confocal scanning microscopy
• Profilometers
• Nanoindentation
• Micromanipulation
• Ultramicrotomes
• Ultra-precise scales
• High-end audio - such as turntables & CD players

The halcyonics_i4 is a state-of-the-art active vibration isolation system: ideal for isolating high-resolution measurement equipment from building vibrations and other disturbances.

The low-profile design belies its capabilities; which include automated locking for transport and fully automatic load adjustment. The latter ensures that it only takes a few seconds to start up the halcyonics_i4, with no adjustment or tuning necessary.

The halcyonics_i4 uses low voltage electromagnetic actuators for active vibration isolation in all six degrees of freedom, so no compressed air is required, and it is controlled by just three self explanatory buttons.

Nano Series

Applications

• Scanning probe microscopy: AFM, SPM, etc
• Langmuir–Blodgett (LB) troughs
• Nanoparticle analysis
• Ultra-precise scales

Combining the best in performance into a system with the smallest dimensions was one aim for Accurion's halcyonics Nano series. The other was an excellent cost-performance ratio. This was achieved with the Nano_20, the world's smallest active vibration isolation unit.

Designed for small and lightweight applications, for example - atomic force microscopy, the Nano_20 and the slightly larger Nano_30 are easy to set up and use as they do not require any tuning or load adjustment.

The active vibration isolation takes effect at 1 Hz and increases considerably from this frequency upwards. Above 15 Hz, halcyonics_nano systems achieve an isolation of 40 dB – which means that 99% of vibration is effectively isolated.

To maintain compactness and improve performance, the Halcyonics Nano series use external controllers. The major advantages of this arrangement for your application are:no heat is generated within the isolation unit, and any potential EMC interference from the control electronics is minimised.
