WebNov 20, 2012 · The transmission of light into the skin was 55, 85, and 93 % with 405, 532 and 635 nm respectively, at a skin depth of 0.08 mm in the very fair skin type. However, in the dark skin type, with the same depth and sources of laser, the transmission of blue, green, and red lasers photons into the skin was 2.5, 10 and 29 % respectively. WebOct 31, 2002 · A diffusion of the immersion agent into the skin depth involves the equalising of the refractive indices of the structural elements of near-surface skin layers, which in turn causes a decrease in the scattering intensity and a certain increase in the transparency of the upper tissue layers.
