Schäfter+ Kirchhoff ships all collimators prealigned and collimated for either a specific wavelength defined by the customer or a typical wavelength. The collimation is performed using professional collimating telescopes.
However, it might be necessary for a customer to readjust the collimating setting and collimate for another wavelength or simply readjust the collimation setting without having a professional collimating telescope at hand.
The following describes some tricks and tips for the collimation adjustment of single-mode, PM or multimode fibers. Please note that single-mode and PM collimation is significantly different than multimode collimation.
