I am looking for a copy of "Minus CX Optics" by D. Orthogon & D. Tillyer
Does anyone know where I can get a copy? Is there a text book that includes this article. Google came up empty.

Check out Dick Whitneys AO web sites at http://www.dickwhitney.net/RBWAOHistoryIndex.html.
It may be a reference to a research paper as well, I would assume that orthogon was not a name since it is a term used in optics quite often. Maybe a search for all of tillyer's works might give you another avenue to search.
Orthogon was Bausch & Lomb's trade name for their plus-cylinder glass lenses. They were all over the place until the early/mid 1970s when minus-cylinder became the norm. Many of us oldsters had to hand hold patients through the plus-to-minus-cylinder conversion. That was especially hard when they were wearing hi-index glass, like Thinlite. Probably Harry Jillson remembers this well too. I can still remember the red and white envelopes that the Tillyer Masterpiece (minus cylinder from AO) and the B&L Orthogon (plus cylinder) came in. As far as I know there was NO Dr. Orthogon.
Lost and confused in an optical wonderland!
Dick,
No links on the site really, but there is a folder that I found that had some documents in PDF, so thanks:

Wilbur Rayton designed the Orthogon lenses for B&L. John Davis designed the Tillyer Masterpiece lens for AO.As far as I know there was NO Dr. Orthogon
Best regards,
