C-6 :
if(PD.type
is knife-edge)
{
DearZoneSpec. < 0.59*(WaveLength)/(ObjectiveLens.NA)*
2/(ObjectiveLens.FocalLength)*0.01 }
- Only applies if knife-edge
- so only when
design decision for a knife-edge PD is valid
- maintained by Redux
- if PD design is changed, possible to
change Objective Lens
Engineer is notified of changes and
Constraint Propagation is not done
unnecessarily.
