WebJun 24, 2024 · where OPD is optical path difference. [L]et's assume we are given two waves f ( x, t) = A cos ( k x − ω t) and f ′ ( x, t) = A ′ cos ( k ′ x − ω t). Their phase difference at a given point x would obviously be δ = ( k ′ − k) x = 2 π λ ( n ′ − n) x WebThe optical path difference (difference in phase) is the total phase accumulated by one wave, minus the phase accumulated by the other. So while one part of the wave goes into the second medium, by the time it …
Webters (nm). Note that the difference in path length for the O and E rays has been neglected in this calculation. In fact, for calcite the angle is only about 5°, so the path length difference is only about a factor of 0.005. For most other minerals the angle is much smaller.

The geometric length is simply the physical distance the light travels. The optical path length is important because it allows us to find out what the phase of the light will be at any point, whereas the geometrical length doesn't. c1 = n * c2.
