PMMA红外滤光板的基础基材为PMMA树脂，通过添加纳米级红外通透因子、功能助剂进行复合改性得到，相较于普通PMMA材料，具备特殊的光学过滤性能。海越PMMA红外滤光板采用医用级PMMA作为基础基材，配合功能助剂复合改性，兼顾光学性能与可靠性。

Q1: What should I do if the PC infrared filter plate turns yellow? The yellowing of PC infrared filter plates is mainly caused by material aging due to long-term use in high-temperature and ultraviolet radiation environments. If the yellowing is slight and has little impact on infrared transmittance, it can continue to be used.

In today's era of rapid technological advancement, infrared technology has been widely integrated into various aspects of life, ranging from smart homes to industrial automation, from security monitoring to medical equipment. As the key foundation for realizing infrared functions, infrared penetrating through polymer materials is playing an increasingly important role. Among them, PC (polycarbonate) and PMMA (polymethyl methacrylate)
