Optical Path Length (OPL) Calculator
Posted by Dinesh onUse this simple optical path length (OPL) optics calculator to estimate geometric length of the path light follows through the system, and the index of refraction of the medium through which it propagates online.
Optical Path Length Calculation
Formula:
OPL = n×d
where,
n - medium of constant refractive index,
d - path of physical length,
OPL - optical path length.
