Semantics is important when you're trying to change the definition of a word that is rigorously defined. Your assertion that the bumpy piece of plastic in the article focus's or disperse's light is false because it does neither, it diffuses light. Focus and disperse have very specific meanings in physics that are not met by an arbitrary piece of material.
If you're confident that a diffuser meets the physical definition of a lens could you point me to reference material that is from something a bit more rigorous than ylighting's webpage? I have yet to see any physics source refer to a diffuser as a lens, Edmund Optics [0] is very precise in their aversion to using that term for a diffuser.
I have yet to find any physics texts that indicate a diffuser is a lens. Please correct me if you have a source because ylighting looks like a commercial supplier using the same imprecise language that you were.
I am happy to stand corrected but I'm not okay with the top comment on a science article undermining scientific definitions.

- crusso 9y agoSemantics is important when you're trying to change the definition of a word that is rigorously defined I'm not changing the meaning of "lens". First-of-all, I don't have that kind of authority. Second-of-all, the bumpy plastic is clearly being used as a lens. The bumpy plastic is used to focus light onto the sensor array in a novel way that allows the resulting sensor image to be used to construct 2D and 3D images. A lens focuses or disperses light, normally to form an image. That's what is happening here in this device. Just because the lens shape is irregular, unplanned, and not a standard one you'd find in a camera shop doesn't mean it's not a lens. reference material that is from something a bit more rigorous than ylighting's webpage That was just one of many examples of references to "diffuser lens". Feel free to do some googling.
