Features

The fiber collimator is designed for collimating radiation exiting from an optical fiber cable or used in reverse for coupling a beam into an optical fiber cable. It has an integrated TILT adjustment to prevent aberrations from vignetting or clipping.
  • Large beam diameters: Focal length 100 mm
  • Optics type: Doublet optics, Achromatic
  • AR-Coating: 400 - 1000 nm
  • Inclined coupling axis, FC-APC connection
  • Integrated TILT adjustment to prevent aberrations from vignetting or clipping
  • Front connector accepts attachment optics

Description

The fiber collimators series 60FC-T is 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.
The features of the collimator type 60FC-T include:

Optics
The achromat with focal length 100 mm is designed for collimating multiple wavelengths. It is AR-coated from 400 - 1000 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 and TILT
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. Additionally attachment optics of series 60FC-T can be mounted to the front of the collimator. Additionally, the collimator has an integrated TILT adjustment for aligning the beam axis to the mechanical axis. This prevents vignetting of the collimated beam as well as diffraction arising from the clipped beam.

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-T is made from nickel silver/aluminium (standard)

Mounting
The collimator possesses a flange for low-strain mounting e.g. using the clamp collars series CC.
