WebA typical cell in monolayer culture has a thickness around 5 micrometers and a refractive index of approximately 1.36. The cell is surrounded by a nutrient medium having a refractive index of 1.335, which yields an optical path difference of 0.125 micrometer, or about a quarter wavelength. Subcellular structures produce much smaller retardations. WebThe refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v. It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam.
