Why my system is not optimized for on axis but another field point?


hjalp

Hi, I am trying to design a telescope system. I am adding fields to 0, 0.07 and 1. My main problem is whenever I do an optimization second field is optimized better rather than point 0. What can i do to optimize for my main point?

To add to what Mike has said, if you are using the weights in the Field Data Editor and the operands are generated by the Optimization Wizard, you’ll want to re-run the wizard after changing the weight of a given field. Many operands that work with fields use specific Hx, Hy values for a given operand, and the wizard scales the weights in the merit function for these particular Hx, Hy values via the weight you provide.

If you are working with operands that take a field number directly, you can weight that operand directly.

Increase the field weighting for the field points you want to emphasize.  You have to experiment some to get what you want.  Try

0°        weight = 3.0

0.07°   weight = 1.0

0.1°     weight = 2.0
