Single microscopic dust particles landing on a warm lens surface create black specs, causing total optical part rejection. Operating positive-pressure cleanroom molding cells with multi-stage HEPA filtration maintains pristine air quality during plasticization and drop-packaging. Automated three-axis robots handle molded lenses directly, eliminating manual handling risks and skin oil transfers.<\/p>\n<\/section>\n<p><!-- FAQ Section --><\/p>\n<section id=\"faq\" style=\"margin-bottom: 40px\">\n<h2 style=\"font-size: 28px;line-height: 1.5em;font-weight: bold;margin-top: 40px;margin-bottom: 24px;color: #111111;border-bottom: 1px solid #eaeaea;padding-bottom: 8px\">\u0627\u0644\u0623\u0633\u0626\u0644\u0629 \u0627\u0644\u0634\u0627\u0626\u0639\u0629 (FAQs)<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-2791\" src=\"https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/07\/measuring-plastic-optical-transmittance.webp\" alt=\"measuring-plastic-optical-transmittance\" width=\"1376\" height=\"768\" srcset=\"https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/07\/measuring-plastic-optical-transmittance.webp 1376w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/07\/measuring-plastic-optical-transmittance-300x167.webp 300w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/07\/measuring-plastic-optical-transmittance-1024x572.webp 1024w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/07\/measuring-plastic-optical-transmittance-768x429.webp 768w\" sizes=\"auto, (max-width: 1376px) 100vw, 1376px\" \/><\/p>\n<div style=\"margin-bottom: 30px\">\n<h3 style=\"font-size: 22px;line-height: 1.5em;font-weight: bold;margin-top: 24px;margin-bottom: 12px;color: #111111\">What causes birefringence in optical plastic molding?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Birefringence is caused by residual molecular stress trapped inside the polymer during rapid cooling or high shear injection. Raising mold temperatures and optimizing packing pressure profiles allows polymer chains to relax, eliminating double refraction in transparent parts.<\/p>\n<\/div>\n<div style=\"margin-bottom: 30px\">\n<h3 style=\"font-size: 22px;line-height: 1.5em;font-weight: bold;margin-top: 24px;margin-bottom: 12px;color: #111111\">What is the difference between SPI A-1 and SPI A-2 mold finishes?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">SPI A-1 polish represents the highest optical mirror finish, polished with 3-micron diamond paste on hardened steel. SPI A-2 polish uses 6-micron diamond paste, leaving micro-scratches that are unacceptable for high-transmittance optical lenses.<\/p>\n<\/div>\n<div style=\"margin-bottom: 0\">\n<h3 style=\"font-size: 22px;line-height: 1.5em;font-weight: bold;margin-top: 24px;margin-bottom: 12px;color: #111111\">Why is PMMA preferred over PC for light guide applications?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">PMMA provides higher light transmission (92% vs 89%) and lower optical chromatic dispersion than PC. However, PC is chosen when superior impact resistance or higher heat deflection temperatures are mandatory.<\/p>\n<\/div>\n<\/section>\n<\/article>","protected":false},"excerpt":{"rendered":"<p>Flawless light transmission in optical lenses, light pipes, and sensor covers requires strict control over polymer purity and molding thermal dynamics.
