Fiber coupler (fiber port) with system mount Ø 19.5 mm for multi-mode fiber coupling.
  • For multi-mode fiber cables or applications that do not require TILT adjustment
  • System mount Ø 19.5 mm
  • Integrated focusing adjustment
  • Focal lengths up to 18 mm
  • Choice of aspheres, monochromats, achromats and apochromats
  • Various AR coatings for UV - IR
  • Choice of fiber receptacles: FC PC or FC APC (standard), many others available


    The fiber collimators series 60FC-A19.5 are designed for compact and long-term stable coupling into multi-mode fiber cables. If used as collimators, please note that for multi-mode collimation the intensity profile is not Gaussian and depends on specific fiber and radiation properties.

    An optics for each application
    A large variety of collimating optics allows that the optimum focal length and the best lens type for a single wavelength (asphere, monochromat) or a wavelength range (achromat) can be selected for each application. All lenses are AR-coated.

    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 coupler can be equipped with FC PC, FC APC, ST or SMA receptacles. In case of FC with a spring loaded ferrule the fiber coupler has an additional grub screw to increase pointing stability.

    The fiber collimators are available in nickel silver.

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