losses. Once the unit is mounted, then the electrical connections can be made. At the very
least, the unit needs +12VDC power at 300mA and serial (RS232) connections made.
Refer to the electrical connection tables. Once the electrical connections are made and the
unit is powered on, communication can be established by either running the AF91x
software or using an appropriate terminal program such as HyperTerminal. Refer to the
communication section of the manual for details on operating the unit via RS232
connections.
When adding the AF91x to an infinity corrected beam path, the laser diode should be
adjusted so that it enters the objective lens aperture correctly. If it does not enter the
objective lens on axis, then performance may be reduced. It is assumed that some kind of
beam combining optic is used on an adjustable mount. This optic should be adjusted so
that the laser diode beam at the entrance of the objective looks like the following image.
Figure 4 Laser Beam Centering
Be sure that the laser diode does not cross over the centerline of the objective aperture
otherwise performance may be reduced.
