Sigmadyne SigFit 2020R1h

The Sigmadyne development team is pleased to announce the availability of SigFit 2020R1h is an engineering analysis tool that integrates mechanical analysis with optical analysis.


SigFit allows users to perform opto-mechanical analyses on finite element results 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.

SigFit has many other features as well including simulation of adaptive control, variational analysis using Monte Carlo methods, and calculation of dynamic responses wavefront error (with link to optical analysis software) and line-of-sight error.

Overview of SigFit


Sigmadyne, located in Rochester, NY, specializes in optomechanical consulting services with decades of experience in many photonics markets. Our software, SigFit, allows users to transform results from mechanical finite element analyses into result import formats for popular optical analysis tools.
