Optical Polyimide Resin <OPI>

Image of <OPI>
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
