Our magnetic-bearing choppers can be operated in a vacuum, in air or in a noble gas atmosphere. The ability to control ultra-high speeds in combination with our magnetic bearing technology allows us to achieve maximum speeds and chopper frequencies. These Choppers are used in infrared, laser, X-ray and VUV radiation for applications such as (serial) macromolecular crystallography (MX, SMX), Coherent soft X-ray Scattering (CSX), resonance enhanced atomic force microscope infrared spectroscopy (RE-AFM IR), to shape and isolate pulses and offer highly stable speed control and lock-in functionality.
The high rotational speed and thus circumferential speed enables fast shutter times of chopper discs and high chopper frequencies. Vibration emissions are kept to a minimum by means of the magnetic bearing technology based on Lorentz force. The rotor position is thus kept very precisely and the stable speed control results in minimal jitter and beam deviation. The proprietary modular magnetic bearing concept allows custom chopper discs and mirrors to be designed and integrated, depending on the application and specification.
Other possible fields of application are the use of technology for vibration-free reaction wheels in communication satellites in space and LIDAR systems for autonomous driving.
