The photostabilization and cure kinetics of UV-curable, optical resins containing various formulations of photostabilizers were investigated to determine the system with the highest cure conversion and durability. Photo-DSC analysis revealed that increasing the concentration of a UV absorber (UVA) decreased both the cross-link density and the cure rate due to competition for the incident photons between...
In diamond turning for the manufacture of optical surfaces, a certain degree of relative vibration is inevitably encountered between the tool and work, deteriorating the surface quality. In this paper we first describe how the tool vibration affects the surface profiles in microscopic level, and then propose a metrological scheme to identify any existence of tool vibration with a minimum effort of...
