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.
