We present a novel optical fiber dynamic light scattering measurement system for nanometer particle size. A multimode fiber probe is used to highly efficiently couple and deliver laser light, while a single-mode fiber probe is used to only receive single scattering light. This design not only improves the measuring ability of the system but also provides flexibility in choosing scattering angle for measurement. By using this system, four kinds of polystyrene nanoparticles are evaluated. Experimentation shows the measured sizes of the nanoparticles are well consistent with the nominal ones, verifying the feasibility of the system.

If the surface of a lens injection mold contains defects, the conditions of its surface coating worsen with each injection in the lens production process. Hence, an on-machine quantitative evaluation method is required for the lens mold surface. With the aim of characterizing the mold surface texture in this study, we have developed an automated light-scattering measurement system that enables 3D detection of scattered light in various directions due to the flaws and roughness of the mold surface.
