Optical diffuser ray diagram
WebOptical diffusers can have different geometrical shapes, adapted to different applications. For example, there are diffuser plates, normally either with a circular or rectangular area and a small thickness of e.g. a few millimeters. Also, there are diffuser coatings which can be applied to various kinds of surfaces, e.g. of metals or plastics. WebMar 31, 2024 · The phase at each diffraction zones will differ exactly by +2*p or -2*p radian from the adjacent zones as shown in figure (a) of the image below. 1. Run the macro “Phases.zpl” and specify surface #2 when prompted. The result shows that there are 246 zones with the last zone being at 14.94 mm from the vertex of the surface.
