Meta-surface corrects for chromatic aberrations across all kinds of lenses (1 Viewer)

Hi,

thanks for the link - did know about nonlinear optics using metamaterials for larger wavelengths but didn't know yet that they were down to visible yet.

The interesting question is when and where this will hit the market. My guess is unfortunately not anytime soon and not for sports optics...

Reasons being:

a) durability - these nano structures are probably quite a bit less durable than a lotus coating, let alone a regular multilayer coating

b) sports optics is not really a challenging field optically - you usually design with the desired features, optically good enough and as cheap as possible here - pushing the limits is done in other fields like microscopy, military optics or large telescopes.
