Abstract
Commercially available optical photoresists for femtosecond direct
laser writing are mostly transparent and only cover a small range of
optical properties. This limits the design possibilities of
micro-structures and micro-optics. Although the fabrication of
3D-printed micro-optics has become state of the art, the field of
spectral filtering seems to be widely unexplored. In this work, we
present, evaluate and compare different methods that can be used to
fabricate colored micro-elements based on the already available
polymers by adding pigments or dyes to the photoresists or by dyeing
the fabricated structures in a post-printing process. Both optical
performance and spectral filtering results are promising and could
enable integrated color filtering or hyperspectral imaging in the
field of 3D-printed micro-optics.
