The fiber collimators series 60FC-F is designed for collimating radiation
exiting optical fiber cables with high pointing stability. They can also be used
in reverse-mode as fiber incouplers. They are suitable for single-mode and
polarization-maintaining fiber cables leading to collimated beams with a Gaussian
intensity profile.
The features of the collimator type 60FC-F include:
Optics
The
achromat
with focal length 12 mm is designed for collimating multiple wavelengths.
It is AR-coated for 630 - 980 nm.
It is corrected for spherical aberrations and designed to be diffraction-limited
over a wide spectral range. That means that it leads to a diffraction-limited beam
with an M2 < 1.05 if combined with typical high-quality single-mode fibers.
Additionally, it is corrected
for chromatic aberration so that there are certain wavelengths or wavelength
ranges where the focal length does not vary significantly. It is not suitable
for UHV applications.
Fine-thread adjustment of focus
The distance between fiber end-face and collimating optics is adjusted using a
fine-threaded ring. The lens in these fiber collimators is spring-loaded. The
linear bearing ensures that the lens does not rotate when adjusting the focus.
The final focus setting is locked by means of two radially arranged clamping screws.
Optimum lens performance
The angled polish of connectors of type APC is considered by a
pre-angled mechanical coupling axis that compensates the beam deflection and
you can use the lens centrically. This minimizes aberrations simply resulting
from a non-ideal beam path through the lens.
Connector Type
The fiber collimator is equipped with a FC-APC type receptacle.
Because of the spring-loaded fiber ferrule the fiber collimator has an additional grub
screw to increase pointing stability.
Material
The fiber collimator type 60FC-F is made from nickel silver (standard)
Mounting
The collimator can be placed into a standard mirror mount using the corresponding
adapters.
