NOTE: Handle this assembly with care. Avoid contact with exposed optical surfaces. Do
not apply stress to the fiber optic cable. The knurled lock ring requires only
modest torque to correctly secure the connector.
The beam receiver may be mounted in most q , f adjustable optical mounts designed
for a 25.4 millimeter diameter optic. Several models of suitable mounts from a
variety of manufacturers are listed in Section 5.1.
NOTE: The beam receiver is also available with a mounting diameter of 30 mm (BC-3).
Consult your Burleigh representative for more information.
Optical mounts with X-Y as well as q , f adjustments may be convenient in some
laboratory configurations. However, basic q , f adjustments are usually sufficient.
When selecting a mount, please note that there must be a ‘clearance hole’ which is
slightly larger than the coupling head’s main body diameter (0.990”). If such a
mount is unavailable, you can mount the coupling head facing in a direction opposite
to that shown.
Install the beam receiver coupling head in the optical mount. You may have to
separate the BC-1 coupling head from the fiber optic cable to insert it in some styles
of optical mount. To detach the fiber optic connector, loosen the knurled lock ring.
Handle the beam receiver assembly with care.
3.3 BEAM RECEIVER ALIGNMENT
The beam receiver head has a 25.4 mm diameter target disk with a 2.5 mm aperture.
A lens centered behind the aperture efficiently couples a collimated laser beam into
the optical fiber when the axis is properly aligned to the laser beam axis.
Alignment is simplified by two reflections from inside the beam receiver. Accurate
alignment into the fiber can be achieved by centering these reflected spots about the
incoming beam, as shown in Figure 3.2.
