Flat Lens

Postby Reg » Fri Jun 03, 2016 9:04 am

BBC just published an article on some Harvard research that has produced a flat lens.

"In my opinion, this technology will be game-changing," said Federico Capasso of Harvard University, the senior author of a report on the new lens which appears in the journal Science.

The lens is quite unlike the curved disks of glass familiar from cameras and binoculars. Instead, it is made of a thin layer of transparent quartz coated in millions of tiny pillars, each just tens of nanometres across and hundreds high.

Singly, each pillar interacts strongly with light. Their combined effect is to slice up a light beam and remould it as the rays pass through the array.

You mean the astigma lens? Yes I have heard the Heavens come into perfect view now.
Don't fart on me in expectations I will retain your loss in loving care to return it you when you have lost even more of yourself. Now, without the denials and distractions of all other issues you can point to that can never seem to get resolved, just what is the actual problem with you that makes any progress impossible?
