Optical Selection System (OSS)

The OSS white paper presents the Optical Selection System for refractive-index-tuned optical VPP grades, including transparent, translucent and optical-function photopolymers. Optical material selection requires matching refractive index, transparency, colour, haze, curing behaviour, post-processing, surface quality and final geometry. OSS structures optical resin selection around measurable optical requirements rather than generic clear-resin labels.
