Our magnetic-bearing choppers can be operated in a vacuum, in air or in a noble gas atmosphere. This allows us to achieve maximum speeds and chopper frequencies. They are used in infrared, laser, X-ray and VUV radiation applications 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.
