# The parameters below don't necessarily match the current speedmeter
# design, instead they were chosen to match Stefan Danilishon's Matlab
# example for comparison. However, you can easily change the parameters
# to an updated design without problem. No special tuning or so is
# required.

# Some strange sounding component names inlcuding '{p}' and '{s}' are just
# OptoCAD notations and have no special meaning in Finesse.
