IR Print for Security Industry
(OP)
I am developing a a Marking System for the security industry and looking for a Dye or Ink that is visible in the 630mn range. I have been looking at organic fluorescent fluorophore's in the infra-red range but find they are too complex and made for Bio-medical industry thus very expensive. I need a chemical that is water soluble that can be formed into an Ink and invisible to human eye but visible using glasses with 630mn filters under normal ambient lighting conditions. I appreciate that the dye will need to be concentrated since viewing will be bye human eye with filters and not CCTV cameras.
