摘要

The device has optical components (4) arranged on a revolver or filter wheel (2), which is fixedly connected with an actuator. The wheel is moved at its rotating axis, and a sensor controlled external rotor brushless motor in flat configuration is used as the actuator. A contactless magnetic halting device has ferrite units (5) arranged over the circumference of the wheel in a uniformly distributed manner, and magnetic units (6) that are magnetically flow through in the halting positions of the ferrite units.
