COC Amorphous Structure Transparency
Fenómeno do problema
COC's amorphous structure has no chromophoric groups and its transparency is excellent, but processing defects affect the optics.
Análise das causas
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.
Solução
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
Conclusão principal
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
