We measured the refractive index of whole blood and other components, such as serum, plasma, and hemoglobin, based on internal reflection by using a homemade apparatus in the spectral range of 400 to 750 nm.
WebFor acrylic with an index of refraction of 1.49, the critical angle is 42.16°. At incident angles above the critical angle there is no refraction. Instead, the entire ray reflects inside the acrylic. This is called total internal reflection. The laws of reflection and refraction can be used to examine the passage of light through WebThe refractive index is a way to express the optical density of a medium, and it is a useful property for identifying materials of various sorts, as well as for predicting the behavior of …

Web28. jún 2024 · 1 I have a few clear solids I need to measure refractive index on. For example PMMA (acrylic) has a refractive index of approximately 1.48. I suspect that it has to do with projecting a laser through the material at an angle and measuring the resulting angle after the laser passes through the material. Any help would be appreciated. optics Share
