A fly's eye composite lens is an optical device that is used to capture images and is inspired by the insect world. However, if you are looking for synonyms to describe this lens, there are numerous options available. For example, you could refer to it as a compound lens, which suggests that it is made up of multiple lenses. Alternatively, you could call it a mosaic lens, given that it is made up of a series of smaller parts, much like a mosaic. You could also use the term multi-lens system, which accurately conveys the idea that this kind of lens involves multiple lenses working together in concert.
