Abstract
Thanks to a technique of optical neutralisation associated with a transilluinination of the eye, it is possible to study the photoreceptor endings (rhabdomere tips) in the compound eye of live and intact Drosophilae. The success of the neutralisation process directly confirms the idea that the convergence of the dioptric system in each ommatidium is essentially due to the refraction at the corneal outer surface. The remarkable regularity of the asymmetrical receptor pattern throughout the eye (fig. 7) is of functional importance. The divergence angle between the optical axis of neighbouring receptors, and their farfield radiation pattern are shown to depend resp...
