Description

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.
The features of the coupler type 60FC-K include:

Optics
The achromat with focal length 6.2 mm is designed for collimating multiple wavelengths. It is AR-coated from 390 - 670 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 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-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.
