Further observations on the clear zone eye of Ephestia

Horridge, George Adrian


1. The radius of curvature of the facets of the moth Ephestia, measured by scanning electron microscopy, ranges from 13 to 17 nm, with best value at about 14.5 μm. Values of refractive indices, measured by interference microscopy, are as follows, cornea 1.49 to 1.51 almost homogeneous; centre of cone 1.43, middle zone of cone 1.40, outer zone of cone 1.37. 2. Rays were traced through scale diagrams of cornea and cone by use of these values. Rays that are parallel when they strike the facet pass...[Show more]
