Light reflectors that disperse light (NOT a prism), what are they called?
I’m trying to find an item for a project. What is it called?
This device/material/design spreads light via triangle or tetrahedral lattice to reflect light internally before it around until it exits the opposite side. I believe the material can be anything transparent from glass to acrylic. The technology is used in bicycle reflectors, car headlights, and possible reflective gear.
Thanks,
^_^
Sorry, but I’m not quite sure what your question is.
Thus to me it appears to touch on several different optical principles.
For the application you cite where the light has to be transmitted through the material, as in car headlights, the design concern is beam shaping which is controlled in part by the lens in front. The optical principles used there are both Fresnel and prism optics. Since you ruled out the prism aspect, the term you may be looking for is ‘Fresnel’.
For systems that depend only on reflected light such as bicycle reflectors and reflective clothing patches, the term you may be looking for is ‘retro-reflector’ or ‘total internal reflection’.
These are systems that rely upon geometry such as corner cube reflectors or glass-beads with total internal reflection to bounce the light back 180 degrees.
Hope this is of some assistance. Gregg
