Injection Compression Molded Microlens Arrays for Hyperspectral Imaging

Injection Compression Molded Microlens Arrays for Hyperspectral Imaging

In this work, a polymer microlens array (MLA) for a hyperspectral imaging (HSI) system is produced by means of ultraprecision milling (UP-milling) and injection compression molding. Due to the large number of over 12,000 microlenses on less than 2 cm², the fabrication process is challenging...
