I just want something like the IR pass windows in front of some IR remote controls but with a curvature to it and not flat.
With flat I can just get a flat plastic sheet from Edmunds or Thorlabs and get it CNC cut to shape but for this I'll need either plastic pellets with the dye/ink blocking the visible light spectrum already added or sold separately with instructions how to mix so I can do injection molding for the custom shape.
Any ideas where I can find either? Couldn't find any help on this elsewhere so although this is a laser-centric forum this relates to light so maybe someone can suggest something.
