Optical distortion of PMMA injection molded parts
Problem Phenomenon
The view through PMMA optical products is distorted and deformed.
Cause Analysis
Uneven product surface, uneven thickness or internal stress causes local changes in refractive index.
Solution
High-precision mold machining; optimize filling uniformity; anneal to eliminate stress.
Key Takeaway
PMMA optical distortion is a fatal defect for lenses and the like.
