Abstract

In 3D printed optics based on UV curing resins there is the chance of inhomogeneities within the material with respect to the refractive index. The talk introduces an extension of the previously used Scanning Focused Refractive Index Microscopy with circular focus to a line focus to measure the refractive index distribution. The line focus brings a speed advantage as it enables profile measurements in a single image. Results from 3D printed samples but also GRIN samples are presented. Additionally, the presentation includes a possibility to do live measurements of the refractive index change during curing to characterize resins.
