WebSep 23, 2024 · The geometric waveguide is based on traditional optical design and manufacturing which implemented one-dimensional exit pupil expansion to accommodate larger interpupillary distance range. The representative is the Israel company Lumus, who has demonstrated FOV up to 55 degrees with superior image quality.
A fixed focal length lens, also known as a conventional or entocentric lens, is a lens with a fixed angular field of view(AFOV). By focusing the lens for different working distances (WDs), … See more In many applications, the required distance from an object and the desired FOV (typically the size of the object with additional buffer space) are known quantities. This … See more Generally, lenses that have fixed magnifications have fixed or limited WD ranges.
