A major advantage of Halcyonics active systems is the lack of an interfering natural low-frequency resonance that is generated by passive systems. These have a more or less marked resonant Eigenfrequency, typically in the range from 1 to 5 Hz. As a result passive systems amplify vibrations in this frequency range. Compared with passive systems, Halcyonics active systems deliver excellent vibration isolation characteristics right at exceptionally low frequencies of 1-4 Hz. They actively isolate vibration for all the 6 existing degrees of freedom.
One application example for Vario systems is the combination of isolation elements with optical breadboards, to be used for Laser applications such as interferometers, holographic assemblies and more. Other examples can be found in many different markets: optical profilers in nanotechnology, UHV scanning tunneling microscope chambers for materials research, smaller 3D coordinate measuring machines (CMM) in production-related metrology as well as high-throughput screening technologies in modern biotechnology. In addition, the Vario elements are used with Patch-Clamp setups, Langmuir-Blodgett troughs, Ellipsometers and experiments in the field of MEMS.
