Question I want to vary the aspheric coefficients of a surface during optimization, but I can't seem to choose the aspheric coefficients when I try to assign variables for that surface. What is wrong? Synopsis Assigning aspheric coefficients as variables for optimization Solution "OSLO requires...
Question "What does "vignetting" mean as it applies to optical design?" Synopsis Definition: vignetting Solution "An optical ray is vignetted when it passes through (or would have passed through) the limiting aperture of an optical system (the system Aperture Stop), but instead gets blocked by some...
