    at the moment, they are too pricey for most applications. But it is just a matter of time before they will be mass produced at low price and then they could well replace curved lenses in most applications because they have certain advantages over them.

    In their current form they are only good for a limited bandwidth, red, some band in IR, green, blue, uv and the like but not all at once at least at this stage of the game.
