I'm trying to find a supplier of infrared filter dye. I found a link months ago, but now I've lost it (bugger). What I'm after is a dye (for use in
screenprinting ink) that will pass infrared light at 850nm, but block most of the visible spectrum. This is just for aesthetics on one of our
products - we want the IR reflector to appear dark to the user.
I know about Epolin Inc. - their dye is $37 a gram !
Does anyone know of (or work for!) any other IR dye suppliers?
