Optical Path Difference (OPD) Calculator
Posted by Dinesh onUse this simple optical path difference (OPD) optics calculator to calculate phase shift which happens between two previously coherent sources when passed through different mediums online.
Optical Path Difference Calculation
Formula:
OPD = [d1×n1] - [d2×n2]
where,
d1 & d2 are the distances of the ray passing through medium,
n1 - is the greater refractive index (eg: glass),
n2 - is the smaller refractive index (eg: air),
OPD - optical path difference.
