Iris  An iris, in the context of optics and photography, refers to an adjustable diaphragm or aperture mechanism used to control the size of the opening through which light passes in an optical system. The iris consists of overlapping blades or leaves arranged in a circular or polygonal pattern that can be expanded or contracted to adjust the diameter of the aperture.
By regulating the amount of light entering the optical system, the iris helps control the depth of field, exposure, and image quality in photography, microscopy, telescopes, and other imaging applications. In industrial lasers and optical instruments, iris diaphragms are used to collimate or focus laser beams, reduce optical aberrations, and optimize beam quality and intensity distribution for specific applications.
