Laser Writes Microlenses on Polyethylene

Hank Hogan

Electronics isn't the only technology where smaller is better. The same is true for infrared optical systems, where microlenses and diffraction gratings improve system performance. Traditionally, these microelements have been constructed using expensive materials or equipment. Now researchers at Centro de Investigaciones en Optica have demonstrated a method that uses local heating from a CO2 laser to shape polyethylene plates into microelements, potentially enabling the mass production of low-cost infrared micro-optics. Researchers have demonstrated that direct writing with a laser on...Read full article
