If link does not work , you can reach to the document with patent number on google patents.
Its a anamorphic lens made from parallel two cylinderical lens elements , first have two positive surfaces , second have two negative surfaces.
I want to design such a large format lens out of acrylic or acrylic and styrene lenses.
Production method is to cut the surfaces with water jet from one piece or two piece transparent plastic block.
I dont have any kind of experience on zemax or oslo and I want the software optimize it for me. I could not find any information on creating cylinderical lenses on software and I have no idea that software does the all , automatically.
I dont know also acrylic or acrylic styrene combination works but
Acrylic have 1.492 index on 587.6 and abbe 57.4
Styrene have 1.590 index on 587.6 and abbe 31.1
I thought styrene can be used as flint and acrylic as crown.
Any advise , help is very welcome.
