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.
  • Large beam diameters: Focal length 60 mm
  • Optics type: Doublet optics, Monochromatic
  • AR-Coating: 390 - 670 nm
  • Inclined coupling axis, FC-APC connection
  • Front connector accepts attachment optics

Description

The fiber collimators series 60FC-L is designed for collimating radiation exiting optical fiber cables with high pointing stability and large beam diameters. 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-L include:

Optics
The monochromat with focal length 60 mm is designed for collimating single wavelengths. It is AR-coated from 390 - 670 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. The focus position varies strongly with wavelength so that the collimator has to be recollimated after any changes to the wavelength. It is not suitable for UHV applications.

Adjustment of focus
The distance between fiber end-face and collimating optics is manually by shifting the lens tube. 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-L can be mounted to the front of the collimator.

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

Mounting
The collimators series 60FC-L all possess a flange for low-strain mounting e.g. using the clamp collars series CC.
