The infinity mirror (also sometimes called an infinite mirror) is a configuration of two or more parallel or angled mirrors, which are arranged to create a series of smaller and smaller reflections that appear to recede to infinity. [1] [2] Often the front mirror of an infinity mirror is half-silvered (a so-called one way mirror), but this is ...
The installation, which is mostly made up of LED lights and mirrors, allows the viewer to "obliterate" themselves and unite themselves with the room. [ 1 ] [ 5 ] It also references the Japanese tradition of hotaru gari — firefly-watching and tōrō nagashi , Japanese water lanterns. [ 2 ]
A convex secondary mirror is placed just to the side of the light entering the telescope, and positioned afocally so as to send parallel light on to the tertiary. The concave tertiary mirror is positioned exactly twice as far to the side of the entering beam as was the convex secondary, and its own radius of curvature distant from the secondary.
Mangin mirrors were used in searchlights, where they produced a nearly true parallel beam. Many Catadioptric telescopes use negative lenses with a reflective coating on the backside that are referred to as “Mangin mirrors”, although they are not single-element objectives like the original Mangin, and some even predate Mangin's invention.
Infinity mirror – Parallel or angled mirrors, creating smaller reflections that appear to recede to infinity; Iterated function – Result of repeatedly applying a mathematical function; Mathematical induction – Form of mathematical proof; Mise en abyme – Technique of placing a copy of an image within itself, or a story within a story
I think it's clear, that the sentence in question must be removed. I am however wondering, whether it is neccessary to write a paragraph about the calculation of the total area and width of the reflections on the mirror (as a replacement for the current incorrect statement).

Instead, the angular aperture of a lens (or an imaging mirror) is expressed by the f-number, written f /N, where N is the f-number given by the ratio of the focal length f to the diameter of the entrance pupil D: =. This ratio is related to the image-space numerical aperture when the lens is focused at infinity. [3]
A convex mirror diagram showing the focus, focal length, centre of curvature, principal axis, etc. A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. [1] Convex mirrors reflect light outwards, therefore they are not used to focus light.
