One of the beams is transmitted through the first mirror and then blocked by the metal cover. If
necessary – this cover can be removed. The beams then travel in the same direction, separated horizontally
or vertically by ~13 mm (Figure 20).

5.9 Computer Controllable Motorized Stages
There are 6 automated stages inside the OPA device that control the angle or position of several
optical components.
Additional wavelength extension modules will require extra motorized stages. They are described in
the manuals of those modules. Currently, up to 12 motors can be controlled by a single USB control board.

The figure above shows the positions of the motorized stages, and the table below describes their
use in wavelength tuning.
