Using the law of reflection – the angle of reflection equals the angle of incidence – we can see that the image and object are the same distance from the mirror. It's actually a parabola. One should mention that the outer surface of the prismatic reflectors of the instant invention should be protected from damage and that can be easily achieved with a wrapping film that contacts the prisms at the (already lossy) apexes, or by any contact-less external enclosure 74 as shown in FIG.

Real-world situations can be modeled using the standard equations of parabolas. A car headlight mirror has a parabolic cross section européenne. When the light direction is in the opposing direction, it is best to use the smaller concentration ratio concentrator as the controlling structure, and terminate the longer concentrator at the point of termination of the short concentrator (with the smaller concentration ratio), namely the prismatic reflectors 63 and 64.
A Car Headlight Mirror Has A Parabolic Cross Section Of One
But it's going to reflect that light diffusely. 3 is a cross section through a prismatic refractive reflector of a circular CPC; FIG.
