Marginal Ray height => when Pupil Zone setting is 0, you are focus on paraxial focal plane; useful when your system is close to paraxial region. If Pupil Zone is not 0 real ray tracing is used, In general, it' risky to use this option as you only use marginal ray to determine where you focal plane is going to be. j<*7p:L7_>

quick focus: this is take you to the location where RMS Spot Size is minimum. P:4"~ ]}
