The Optics of the Compound Eye of the Honeybee
The Optics of the Compound Eye of the Honeybee

... Morphology The optical apparatus of a bee's ommatidium (Fig. 1) consists of a cuticular lens, a crystalline cone, and principal pigment cells. The cuticular lens is a laminar, chitinous, transparent structure secreted by the principal pigment cells. Beneath the lens lies the crystalline cone which e ...

Nonimaging optics

Nonimaging optics (also called anidolic optics) is the branch of optics concerned with the optimal transfer of light radiation between a source and a target. Unlike traditional imaging optics, the techniques involved do not attempt to form an image of the source; instead an optimized optical system for optical radiative transfer from a source to a target is desired.
