WebOptical Path Difference (OPD) is the difference between the two beams travelling through the two arms of an interferometer. OPD is equal to the product of the physical distance travelled by the moving mirror (multiplied by 2, 4, or other multiplier, which is a function of the number of reflecting elements used) and n, the index of refraction of the medium … Webmaximum birefringence in nm/cm. OPD due to stress birefringence is a*σ*K, where a is path length in cm, σ is residual stress in N/mm, and K is difference in photoelastic constants in 10-7 mm / N. A retardation > 20 nm / cm corresponds to a coarse anneal, and a retardation of < 10 nm/cm is a fine anneal. Part 3 covers bubbles and inclusions.
