Fabricating Precise Polymer Optics

Facebook X LinkedIn Email
Microlens arrays manufactured using polymer injection molding and a highly precise micro-cutting process are ideally suited for LEDs, smartphones and consumer electronics.

OLAF KRAFT, JENOPTIK POLYMER SYSTEMS GMBH

Polymer optics are one of the cornerstones of photonics, driving the innovation necessary to meet the requirements for ever-smaller installation spaces and significant weight savings, all while achieving a higher image quality. The miniaturization of optics using micro-structured surfaces today can be found in many areas including smartphones, LED lighting and consumer electronics, where these attributes are particularly important. Compared to glass-based optics fabricated using traditional manufacturing methods, there are numerous advantages of polymer-based optics manufactured by...Read full article

    polymerization
    Process of synthesizing long molecular chain materials (polymers) by reaction of many small molecules (usually thousands) called monomers.
    injection molding
    A method of producing high-quality plastic optics in large volumes by injecting the heated, liquified plastic at high pressure into a tooled mold with polished chromium stainless steel inserts to define the optical surface. The plastic solidifies as it cools, and the mold is removed.
