UV marker additive
UV marker additive
(OP)
All,
We are trying to use a vision system to inspect some plastic parts that are molded white. When it comes to inspection systems the most difficult color to work with is white. I am wondering if there are any UV additives that will show up under non visible light?
Regards,
Rich.....

RE: UV marker additive
Lots.
Ciba Geigy or whatever they call themselves now will have an extensive range. They might also be known as OBAs or optical brightening agents.
They work by absorbing light in the UV range and re emitting it in the visible range, normally in the blue region.
