Non Invasive Blood Detection

Eddy
Hi All,

im looking for a way to detect blood in plastic surfaces without the use of chemical agents like luminol, is there any machine that can detect blood presence without using chemicals??

Thank You

You can use a forensic light source for blood also.  But it doesn't glow.  The blood will absorb the light and appear to be darker than the surrounding area.

forensic alternative light source 405nm-415nm, and laser 405nm, they are better to detect blood stain, laser 405nm is the best. blood has high absorption, will occru as a dark spot when it was exposed to any type of light.
here are videos to show how lasers and ALS applied in blood stain, fingerprints, urine, saliva, semen..
