WASHINGTON -- In a new study, researchers have shown that 3D printing can be used to make highly precise and complex miniature lenses with sizes of just a few microns. The microlenses can be used to ...

For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and ...

(Nanowerk Spotlight) Optical lenses play a crucial role in a vast array of applications, from microscopy and astronomy to photography, medical devices, and machine vision systems. Traditionally, the ...

Researchers detail how they used a type of 3D printing known as two-photon lithography to create lenses that combine refractive and diffractive surfaces. In a new study, researchers have shown that 3D ...
