Insect compound eye,coloured scanning electron micrograph (SEM). The units in a compound eye,the ommatidia,each contain a cornea and photoreceptor cells,and are capped by a cuticular biconvex lens. It is the cumulative effect of these that produces the vision of a compound eye. A compound eye is not very good at distinguishing detail,but it does enable the detection of tiny movements. This is one of the compound eyes of a heteropteran insect. Magnification: x150 when printed at 10 centimetres across | |
