WebThe f/# of the lens controls how quickly the cone expands and how much information or detail is blurred together at a given distance. Figure 3a shows a lens with a shallow DOF, where Figure 3b shows a lens with a large DOF. Figure 3: Geometric representation of DOF for high and low f/# lenses. Web3M folded optics Birefringent reflective polarizers are used to produce compact, mid field-of-view (FOV) eyepieces and wide FOV optics for VR head-mounted displays using folded optics in the lens configuration. Multiple configurations for folded optics lens systems may be optimized, with advantages and disadvantages relative to refractive systems.
