Description

The fiber collimators series 60FC-A19.5 is designed for compact and long-term stable coupling into multimode fiber cables. If used as collimator, 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-A19.5 include:

Optics
The achromat with focal length 12 mm is designed for coupling multiple wavelengths. It is AR-coated from 980 - 1550 nm. It is corrected for spherical aberrations and designed in such a way that it leads to a diffraction-limited spot 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 coupling 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-A19.5 is made from nickel silver (standard)

Mounting
The coupler is compatible with system mount 19.5. They are also compatible with the multicube system where a tilt alignment is not required.
