Optical skin depth
WebBetween 400 nm ≤ λ ≤ 500 nm, gold’s skin depth is increasing with longer wavelength to just about 490 nm, implying that the blues and greens are more likely to interact with the bound electrons and get absorbed.

WebSep 12, 2024 · In the penetration depth of 1%, the intensity is reached at 5378 μm (5.4 mm) with a wavelength of 750 nm. This is in agreement with literature which states the penetration of optical light systems reaching to a depth of 4–6 mm [ 8, 28 ]. WebIt has been estimated that 4% to 7% of visible light is reflected from the surface of the skin, independent of wavelength and skin color. 43,44 The remaining light is refracted as it …
