Application of DWL66+ grayscale lithography in micro-optical element fabrication
by Ava Faridi
A novel study by Prof Menon and his team on micro-optical element fabrication
The findings push photolithography and imaging beyond the diffraction limit and developing optical elements for photovoltaic systems. In this project, the multi-level diffractive lens was patterned using grayscale-optical lithography via a laser-pattern generator, DWL 66+ Heidelberg Instruments.
