Dear @David ,

 

Thank you for taking the time to double-check what I did. It seems like I’m not completely crazy yet. I will try some of the other embodiements described in the patent and keep the post updated.

Take care,

 

David

Hi David,

I can’t see any problems in what you’ve done. I checked the LDE against the patent -- looks right. I optimized the lens with the first airspace (working distance) variable -- the OPD reduced to 10 waves, still terrible. Wondering if it could be for a 160mm tube, I optimized for a focal image space with front and back airspaces variable -- the optimum air spaces were inconsistent with a valid tube length and the OPD still terrible.

Perhaps the prescription give in the patent isn’t correct.
