👉 The term "iridial" is a name given to the concept of an optical device that consists of two mirrors, one at each end of a light source. The purpose of this arrangement is to focus and magnify incoming light waves onto a single surface, typically a screen or an object. In general, the use of iridia elements in optics is not common but can be seen in specialized applications such as optical fiber systems for communication channels, where they are used to transmit light over long
