Abstract
SABIC’s ULTEMTM (polyetherimide) resin has been the choice of material for injection moldable micro lenses and lens arrays in optical communication components such as transceivers due to its unique combination of physical, thermal and optical properties including high refractive index, low absorption in near IR range, good dimensional stability and high heat performance. It's known that processing conditions affect properties of final parts. Often the processing conditions are optimized for best mechanical properties, while their effect on optical properties is sidelined. In this study, the effect of injection molding processing conditions on optical properties of polyetherimide resin is discussed.
