The basis of the fiber alignment system is a very stiff setup with an H-811 hexapod and an P-616 NanoCube® nanopositioner. The parallel-kinematic design for motion in degrees of freedom ensures high system stiffness. The motorized drives make longer travel ranges possible and at the same time, the NanoCube® nanopositioner ensures fast scanning motion and dynamic compensation of drift effects. Flexure guides and all-ceramic insulated PICMA® actuators guarantee a long lifetime. Because all drives are equipped with position sensors, it is possible for example, to reliably prevent collisions with expensive silicon wafers.
The sophisticated scan routines are integrated directly into the controller. The performance is improved considerably and integration simplified. The system can manage all tasks in the field of fiber alignment. For example, double-sided systems allow simultaneous alignment of the transmitter and receiver.
The software package supplied in the scope of delivery allows integration of the system into virtually any environment. All common operating systems such as Windows, Linux, and MacOS as well as a large number of common programming languages including MATLAB and NI LabVIEW are supported. Thanks to sophisticated program examples and the use of software tools such as PIMikroMove, the time between starting integrating and productive operation is shortened considerably.
The controller receives the optical intensity signal directly via a high-resolution analog input. Complex setups with cameras are not necessary. Various distribution functions are available for determining the maximum intensity.
