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 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.
Material
The fiber collimators are made of nickel silver and black anodized
aluminum (standard) or in amagnetic titanium. In case of titanium,
the relative permeability is near 1 (µr=1.00005) making it almost
transparent to magnetic fields. The linear coefficient of thermal
expansion is close to that of the optics so that a thermal
stability over a larger temperature range can be expected.
Mounting
All Fiber Collimators 60FC-T with diameter Ø25 mm can be placed in
a standard mirror mount. 60FC-T with a larger diameter posses a
flange for low-strain mounting e.g. using the clamp collars series
CC.
