2. Near-infrared vein finder - Wikipedia

   en.wikipedia.org/wiki/Near-infrared_vein_finder

   Near-infrared vein finder are medical devices used to try to increase the ability of healthcare providers to see veins. [1] They use near-infrared light reflection to create a map of the veins. [1] The received imagery is then either displayed on a screen or projected back onto the patient's skin.

   The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. [1] Within the NIR window, scattering is the most dominant light-tissue interaction, and therefore the propagating light becomes diffused ...
