WebJun 28, 2013 · 613.82 KB Citations (0) A revised Michel-Lévy interference colour chart based on first-principles calculations February 2013 Bjørn Eske Sørensen Last Updated: 05 Jul 2024 As polarised light passes through a birefringent sample, the phase difference between the fast and slow directions varies with the thickness, and wavelength of light used. The optical path difference (o.p.d.) is defined as , where t is the thickness of the sample. This then leads to a phase difference between the light passing in the two vibration directions of . For example, if the optical path difference is , then the phase difference will be , and so the polaris…
