I saw this article today, announcing a mathematical solution for chromatic aberration.

 

Will this mean low-cost, high-quality optics, or simply a new type of high-cost, high-quality optics?

Did you see the equation for this design?  I'm guessing it will be very expensive to fabricate.

I read a couple short threads on it and the consensus among the optics folks is that it will have little if any impact. I can’t tell you why, cause I don’t speak their language, but’s that’s what I took away from it. shrug.gif

Yeah...I intentionally avoided any language which feigned actual smarts related to the topic.  Was hoping some folks here had the chops to chew on it publicly, while I watch and try not to choke on popcorn. 

 

From a position of ignorance, it seemed puzzling that you had to know the distance from the optic to the subject, but who knows, maybe you always need that value and that it changes is why we have to focus.

 

Bobito, you make a good point.  Knowing the shape doesn't mean it's easy to make, but perhaps it can be made of something cheaper, that's way easier to work with than say fluorite, if the shape yielded by the equation inherently wipes out chromatic aberration. ¯\_(ツ)_/¯

I kept telling everyone I was double checking the equation!  lol.gif

 

 

That equation went into the next zip code!

I was originally going to question the opening statement "over two thousand years ago"..as I was not aware "lenses" were produced so long ago. Apparently they were, a quick google search shows papers written on quartz lenses dating back to 750bc.

One Mycenaean/Minoan artifact, the Pylos Combat Agate, is dated from 1450 BCE, and almost certainly would have needed some kind of magnifying lens to create,  The detail is simply too fine and exquisitely crafted at a miniature scale to have been done by the eye alone.
