Fiber Collimators Series 60FC-LSA
This document provides assistance in installing the fiber collimators series 60FC-LSA. It describes how a fiber
cable is attached and how the collimation setting is adjusted.
1.
Before You Start
The laser beam coupler is shipped with a protection cap for the fiber receptacle and with a front cap.
Notice:
There is a polymer cap on the receptacle. Please perform the following steps in order to remove this cap:
Now, make sure that the connector of the fiber you want to attach matches the receptacle type of the laser
beam coupler:
• Use fibers with APC (8°-polish) connectors for laser beam couplers with an inclined coupling axis
(60SMF-LSA-4).
• Use fibers with PC (0°-polish) connectors for laser beam couplers with a coaxial axis
(60SMF-LSA-0).
The laser beam couplers are compatible to all fiber connectors of type LSA, DIN, AVIO and AVIM.

Please remove all the protection caps first and do not use them as beam
dumps (risk of photo contamination).
• Do not touch either the optical surface of the lens or the fiber end-face.
• If the coupler is not in use, reattach both rear and front protection caps.

Figure 1:
First, remove the threaded cap from
the fiber receptacle of the fiber
collimator.
Figure 2:
Then, slightly loosen the small pin
screw. Use the screwdriver 9D-12.
Make sure to not loosen it too far, as it
is small and easily lost.

- Page 3 Fiber Collimators Series 60FC-LSA Attaching a Fiber Cable to the Fiber Collimator For attaching a fiber cable to the fiber collimator perform the following steps: Figure 3: 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...
- Page 4 Fiber Collimators Series 60FC-LSA Figure 7: Finally, gently tighten the fiber grub screw to reduce the free play of the ferrule in the receptacle. The free play in between the connector ferrule and receptacle is only a few microns, but necessary for inserting the ferrule without force.
- Page 5 Fiber Collimators Series 60FC-LSA Adjusting the Collimation Setting Collimation adjustment (adjustment of the collimating lens in z-direction) is a demanding task and should be performed preferably using a collimating telescope. Notice: The fiber collimator is shipped pre-adjusted for the labeled wavelength and, often, it is not necessary for the customer to readjust the lens position.
