Imaging with the multispectral chiral lens forms two images of the beetle, Chrysina gloriosa, on the color camera. The left image was formed by focusing left-circularly polarized light reflected from the beetle and the right image was formed from right-circularly polarized light. The left-handed chirality of the beetle’s shell can clearly be seen. Credit: Image courtesy of the Capasso Lab/Harvard SEAS
Multifunctional lens could replace bulky, expensive machines. Many things in the natural world are geometrically chiral, ie they cannot be superimposed onto their mirror image. Think hands – right and left hands are mirror images but if you transplanted a right hand onto a left, you’d be in trouble. Certain molecules are chiral, including DNA and amino acids.
