Fiber Coupler compatible with kinematix® optomechanics
The fiber collimators series 60FC-K is is compatible with the kinematix®
optomechanics, that can be used for coupling into single-mode or polarization-maintaining
fiber cables or as a fiber collimator. They are suitable for single-mode and
polarization-maintaining fiber cables leading to collimated beams with a Gaussian
intensity profile.
Please note that for multimode collimation the intensity profile is not Gaussian
and depends on certain fiber and radiation properties.
The features of the coupler type 60FC-K include:
Optics
The
achromat
with focal length 4 mm is designed for collimating multiple wavelengths.
It is AR-coated for 980 - 1550 nm and is suitable for 980 - 1550 nm.
It is corrected for
spherical aberrations and designed in such a way that it leads to
a diffraction-limited beam with an M2 < 1.05. 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.
Adjustment of focus
The distance between fiber end-face and collimating optics is adjusted by means
of an eccentric key. 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 SMA type receptacle.
Material
The fiber collimator type 60FC-K is made from nickel silver/stahl (standard)
Mounting
The fiber coupler needs to be placed into kinematix® optomechanics (not included)
in order to be used as in or outcouplers.
