Abstract

Injection Moulding (IM) and Injection Compression Moulding (ICM) are the leading process technologies to enable mass manufacturing of Fresnel lenses. Even though ICM requires a more expensive and complex process, it is proven to lead to higher optical performances in comparison with IM. In this study, tolerancing for ICM and IM addresses the geometrical accuracy and precision of the two manufacturing processes when micro structures of Fresnel lens surfaces are taken into account.
