Not the same thing, but a friend of mine invented an infrared lens based on lobster eyes, with the application being to focus IR energy from heaters down to where it's needed. Ordinary glass doesn't pass much IR, so you can't make an IR lens for this purpose out of glass; and quartz is not practical for other reasons. His lens uses metal reflectors in what amount to tubes, on the model of lobster eyes, to focus the IR. It acts like a lens, not a mirror, in the sense that it's in front of the IR source, not behind it. The company is Radiant Optics.
