Anming Hu Leads Efforts to Invent a New Manufacturing Technique for Microball Lens

Anming HuTwo MABE faculty members have joined forces with Beijing University of Technology in China to invent a simple and innovative manufacturing technique for a microball lens using a femtosecond fiber laser. The microball lens is formed by a gas cavity created from laser irradiation and molecular dissociation of a polymer. This manufacturing approach is much more facile and less expensive compared to conventional stereolithographic methods. These micro lenses and micro lens array are key optic components for micro-optics systems, wide angle/stereo imaging (compound eyes), and super-resolution imaging.

MABE Assistant Professor Anming Hu led the group effort—working closely with MABE Magnavox Professor Kenneth Kihm and Dr. Tao Chen at Beijing University of Technology.

The work was recently published in Small, a highly-rated Wiley academic journal. An invention disclosure covering development of this technology was also filed with the UT Research Foundation.
