Most animals—humans included—have eyes that use lenses to form images. The eyes of scallops are different. A typical scallop eye forms images largely by reflection from a mirror- like surface at the back of the eye. as shown the important features of a typical scallop eye. The lens causes very little redirection of incoming light rays; it is the spherical surface in the back of the eye that brings rays of light to a focus on the cells of the retina. (For simplicity, we’ve shown no refraction by the lens, although the lens does cause some refraction that seems to help to make the image sharper by correcting for the spherical aberration introduced by the mirror.) The reflection is due to thin-film interference from the front and back faces of 80-nm-thick transparent crystals of guanine, index n = 1.83, that are embedded in cytoplasm with index n = 1.34. The individualeyes are quite small. A typical scallop has 40 to 60 eyes, each with a 450-mm–diameter pupil and a reflecting surface at…
