- The absorption spectrum of dry untreated blood has also been measured and a suggested method for enhancement and photography of blood stains is derived from this measurement. The method is presented in the form of a flow chart. Both methods are based on the use of a high intensity light source such as the Polilight.
Polilight - Wikipedia

- Although blood has a high absorption in a very broad region (300 - 900 nm) it has a strong and narrow absorption band with the maximum at 415 nm (Fig. 3.). The E-5 Polilight band (central wavelength 425 nm) is specifically designed to match this absorption band, but it has to be tuned down (from 425 - 415nm) with the inbuilt tuning device.

- The Polilight PL500 is a high-intensity light source based on a 500 Watt xenon arc lamp. This type of lamp delivers UV, visible, and infrared light. A special characteristic of the light output in the visible region is that the intensity of light is the same in the whole spectrum, just like sun light.

- Bloodstains of varying amounts on white cotton were examined under Polilights(415nm/yellow goggles). At this wavelength bloodstains were detectable down to the smallest amount tested: 5mL. The serial dilution of blood on cotton showed that blood is detectable down to a 1:1000 dilution under Polilights(data not shown).
