Reconstruction of objective lenses from the patent

Hi,

I am learning how to reconstruct the objective from the patent. I tried with https://patentimages.storage.googleapis.com/f4/46/e9/67ad0174b44df7/US6501603.pdf Embodiment 3, which looks like  this 

My modulation looks like this

the arrows represent errors ( in my opinion) although the thickness between those surfaces is correct with the design specification, I wonder why this happened. I changed the thickness values ( surface 16 and  24) it looks better but it is not the correct value according to the patent.

How much more I can do with this reconstruction to make sure it is as close as possible to the original specification of the patent? My dilemma is that if I apply a merit function and do optimization, it may change the radius and thickness of the surfaces hence the simulation won’t show the real objective performance. 

Regards,

Marzanna

Hi Marzanna,

 

I just answered your other question. I might suggest you to read my previous topic as well for this question:

People from the community have given me lots of insights as to how I can optimize the design from the patent and it worked really well for me. If you manage to get a good design, please share it with us, and we can start a collection of objective lens design from patents :)

Take care,

 

David
