COC Amorphous Structure Transparency
Fenómeno del problema
COC's amorphous structure has no chromophoric groups and its transparency is excellent, but processing defects affect the optics.
Análisis de la causa
COC is an amorphous high-molecular polymer; there are no chromophoric groups in its structure; it presents excellent transparency to light sources that can excite quantum absorption; its visible light transmittance is comparable to PMMA; but bubbles and impurities affect it.
Solución
①Utilize the amorphous transparency advantage; ②defect-free process; ③impurity prevention and control; ④optical inspection; ⑤quality assurance.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusión clave
COC amorphous transparency is the basis of optical applications; defect prevention and control is the guarantee; inspection ensures optical quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
