Features

The fiber collimators series 60FC-F with fine-focussing mechanism are designed for collimating radiation exiting from an optical fiber cable or used in reverse as a fiber coupler (fiber port) for coupling a beam into an optical fiber cable. The focus adjustment is done using a fine-threaded ring.

  • Focal lengths up to 18 mm
  • Choice of aspheres, achromats and apochromats
  • Various AR coatings for UV - IR
  • Choice of fiber receptacles: FC PC or FC APC (standard), many others available
  • Compact Ø 12 mm housing
  • Focus adjustment using a fine-threaded ring with 0.5 mm pitch

Description

The fiber collimators series 60FC-F are designed for collimating radiation exiting optical fiber cables with high pointing stability. They can also be used in reverse-mode as fiber incouplers. They are suitable for single-mode and polarization-maintaining fiber cables leading to collimated beams with a Gaussian intensity profile.

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. For an ideal Gaussian beam and standard fibers you can reach coupling efficiencies up to 80%.

Adjustment of focus
The distance between fiber end-face and collimating optics is adjusted using a fine-threaded ring. The lens in these fiber collimators is spring-loaded. The linear bearing ensures that 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 can be equipped with FC PC, FC APC receptacles. Because of the spring loaded ferrule the fiber coupler has an additional grub screw to increase pointing stability.

Material 
The fiber collimators are available in nickel silver.

Mounting
The collimator can be placed into a standard mirror mount using the corresponding adapters.
