"...it was Asahi Optical that developed and patented the current process that makes such accurate coatings mass producible." Well, I'm under the impression--from the Contax or Zeiss list, I think--that Pentax didn't really improve upon it all that much; they simply bought the exclusive rights. "I further understand that (at least for some time), companies that desired to produce accurate multicoatings paid a royalty to Asahi Optical. Some companies elected to license only a part of the process, others decided to go their own way." True. You can enjoy the same coatings on your computer monitor by looking for a monitor or glare screen that uses OCLI coating.
