Under this moderately-high magnification of 2827x, this scanning electron micrograph (SEM) depicted the surface of an unidentified insect's compound eye. Discovered diceased on the grounds of the Decatur, Georgia suburbs, the eye is seen to be composed of repeating hexagonally-shaped units known as 'ommatidia', hence the term 'compound'. The white specs on the surface of the eye are merely debris particles of unknown origin. In order to fully appreciate the structural hierarchy of the compound eye, see PHIL 7875, 7877, 7878, this image (7879), 7880, and 7881, for successively greater magnifications of this visual structure.
