Is geometry created in APEX accurate?
CAD programs are accustom to modeling surfaces with mechanical accuracies and tolerances. Optical surfaces require much greater accuracy and tighter tolerances than mechanical surfaces because of the exacting computational nature of the interaction of light as a ray with these surfaces. Mechanical accuracies and tolerances are inadequate to produce precise simulation results in some situations. In contrast, APEX is “optics aware” and allows engineers to create optical geometries common to optical engineering with the required accuracy for simulation.
