Common Defects & First Checks
Silver Streak
PMMA(acrylic): transparent.
Field Notes
PMMA(acrylic): transparent. Optical clarity needs careful drying & clean processing. Moisture → silver streak. Beyond 9-type: crazing, bubbles, haze. Dehumidifying dryer up to 98°C, 2-3h. Mold below 60°C risks surface stress on optical faces.
