I have been researching how to make backlit panels for flight simulators, like this one:
I came across this video:
Where they use cast transparent acrylic and then paint it with "laser color", however I cannot find anything on the internet for laser color, laser paint, laser resistant paint whatsoever.
Came across a post in aviation stackexchange, where they also refer to "white opaque special laser colour" (search for "How are backlit aircraft panels (for simulators) made?", I cannot post more than 1 link now).
I tried myself using painted opal acrylic with black and then grey color, but when the laser hits, it burns the paint and damages the acrylic, which gives it smoked appearance when backlighting is off, as opposed to white.
I haven't tried painting white first, because 1. The acrylic is white opal in the first place, and 2. I'm afraid I will have the same result when the laser hits the paint.
Can somebody provide more insight about the technology and the actual products used? What is that laser color they talk about?
