Blood index of refraction
WebRefractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations.

WebApr 14, 2024 · In the human eye, the average index of refraction of the crystalline lens is 1.386, which is higher than the index of refraction of the aqueous 1.336. This difference helps drive the refractive power of the … WebHowever, selecting the working fluid with blood density and viscosity, and PDMS index of refraction (RI) for such experiments is challenging. Currently, water–glycerol is commonly used and sodium iodide (NaI) is often added to increase the index of refraction without changing fluid viscosity. But the resulting fluid density is well above blood.
