Study of the Effects of Mold Coating on the Birefringence of Injection‐Molded Optical‐Quality Polycarbonate

Polymer Engineering &Science, EarlyView.
Experimental and numerical evaluation of birefringence of injection molded parts ABSTRACT This study investigates the impact of mold surface coatings on the birefringence of injection‐molded optical‐quality polycarbonate lenses. Birefringence, caused by residual stresses during molding, affects optical clarity and performance.
