I'm trying to optimize my vein viewer with LED lights but I'm not sure which factors affect the penetration of the light through the skin. (I'm following this guide https://www.instructables.com/id/How-to-make-an-affordable-Vein-Finder-for-use-d/)
I can say those factors are the angle of the lights, the colour of the skin, swollen areas. Is there anything else I should consider too? And should I use Parallel light beam instead of non-divergence light beam?
The last question I want to ask is about the arrangement of the LED lights. Is it best to arrange them as a circle or a rectangular?
Sorry for my bad English if there is any mistake.
