Answer:
In optics, optical path length (OPL) or optical distance is the product of the geometric length of the path followed by light through a given system, and the refractive index of the medium through which it propagates. In many textbooks, it is symbolically written as Λ.

Answer:
δ = (2π/λ)(OPD)
where π is a constant (3.14159265) and λ is the wavelength of light illuminating the specimen. The optical path difference is the product of two terms: the thickness (t) and the difference in refractive index (n). The OPD can often be quite large even though the thickness of the object is quite thin.
