Fiber Collimator Series 60FC-F
This document assists you in installing the series 60FC-F fiber collimators. It describes how a fiber
cable is attached and how the focus setting is adjusted.
If you want to use the 60FC fiber collimator as an in-coupler, please also refer to document NN.
Before You Start
Ensure that the fiber holding screw does not protrude into the inner cylinder of the fiber receptacle.
This would damage the fiber, especially if the fiber connector is forced into the receptacle despite
the protruding screw.
Use the screwdriver 9D-12 to carefully retract the pin screw out of harm’s way (Fig. 1, left).
Take care not to retract it too far, it is small and easily lost.
Ensure that the fiber cable matches the receptacle type:
-
Use FC-APC (8°-polish) cables for fiber collimators with an inclined coupling axis (60FC-4)
-
Use FC-PC (0°-polish) cables for fiber collimators with a coaxial axis (60FC-0)
Caution:
-
Do not touch the optical surface of the lens nor the fiber end face
-
If the collimator is not in use install both protection caps
-
In order to avoid photo contamination remove the protection caps before you launch
radiation to the fiber collimator
Attaching a Fiber Cable to the Fiber Collimator
To prevent damage to the sensitive fiber end face, always insert the fiber connector's ferrule at an
angle, with the connector key properly aligned to the receptacle notch, as shown in Fig. 1, left.
When the ferrule tip is safely located in the inner cylinder of the receptacle, align the connector to
the receptacle axis and carefully introduce the connector into the collimator. With the connector key
pressed gently onto the right-hand side of the receptacle notch, gently screw the fiber cap nut onto
the receptacle until it is finger-tight.
Then, with the connector key pressed gently onto the right-hand side of the receptacle notch, gently
screw the connector cap nut onto the receptacle until it is finger-tight.
