60FC-0-S24-49

The fiber collimators series 60FC 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 coupler type 60FC include: 

Optics

The monochromat with focal length 20 mm is designed for collimating single wavelengths. It is AR-coated from 250 - 650 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 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 can be mounted to the front of the collimator.

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 is made from nickel silver (standard).

Mounting

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