Fiber Coupler for multimode fiber cables
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
asphere
with focal length 6.16 mm is designed for single wavelength
applications and are corrected for spherical aberration.
It is AR-coated for 350 - 700 nm and is suitable for 360 - 700 nm.
The focus position varies strongly with wavelength
so that the coupler has to be refocussed after any changes to the wavelength.
This lens type is 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.
Connector Type
The fiber collimator is equipped with a FC-PC 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.
