SIGMADYNE

Optomechanical Analysis Software: SigFit allows users to perform opto-mechanical analyses on finite element results from Abaqus such as surface deformations, lens temperatures, and lens stresses. Such results are used within SigFit to compute optical performance metrics such as characterizations of deformed optical surfaces, maps of optical path difference (OPD) due to the thermo-optic and stress-optic effects in lenses, maps of birefringence and crystal axis orientation due to stresses in lenses. These optical performance metrics can be formatted into files readable by many popular optical analysis codes allowing engineers to understand the effects on optical performance due to mechanical disturbances.
