OPI Series is the best fluorinated polyimide as an optical component polymer because of the high optical transmittance as well as the superior heat resistance of polyimide.

Features

• Good optical transmittance
• High heat resistance
• Moisture resistance
• High CTE control
• High controllability in refractive index
• High controllability in birefringence
• Excellent adhesion
• Easy application to substrate
