Figure 3-4. Optical pathway based on filter position.
The position of the Output Galvanometer must be coordinated with that of the Input
Galvanometer to complete the optical pathway to the Light Guide Port (shown above). The
Output Galvanometer angle is also expressed in an arbitrary unit whose value ranges from 0
to 4095. The discrete Output Galvanometer Value that defines the optimal light path for
each of the FILTER POSITIONS has been determined at the factory, and can be found on
the Optical Alignment Data Sheet. The following table shows some typical Galvanometer
Values for each FILTER POSITION.

1 3500 750
2 2500 1500
3 1500 2500

3.7.7.2 Filter Numbers
The Lambda DG-4 uses paired Input and Output Galvanometer Values to define a given
optical pathway. Any pair of Galvanometer Values can be assigned a FILTER NUMBER from
1-15. It is important to remember that a FILTER NUMBER is a “logical filter” and does not
necessarily correspond to the number on the cabinet that labels the FILTER POSITION
through which that optical pathway passes. The Input and Output Galvanometer Values that
define the optical pathway that passes through FILTER POSITION number 4 in the sample
values shown above would be 1000 and 4000, respectively. Those Galvanometer Values could
be assigned any FILTER NUMBER from 1 through 15.
