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 ...

A research team has developed a small optical lens, only a few millimeters in size, whose refractive behavior changes in the presence of gas. This 'intelligent' behavior of the micro-lens is enabled ...

Researchers have developed light-transmitting hydrogel fibers that are just hundreds of micrometers in diameter. With further ...

Optical fibers with integrated robotic microstructures are promising for cutting-edge applications. However, the development of microbots on a fiber system for synergistic sensing and actuation is ...

Endoscopic optical coherence tomography (OCT) is a valuable tool for providing diagnostic images of internal organs and guiding interventions in real time. Miniaturized OCT endoscopes are essential ...

As a structure composed of two-dimensional arrays of microscale lenses, micro-lens array (MLA) has attracted attentions of both the academia and industry, due to its distinctive optical properties and ...

Microlenses are tiny optical devices used to focus light onto cameras and fiber optics. While debugging a different project, I stumbled on a technique that made hemispherical depressions. So I made ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.220025 considers specialty optical fibers for advanced sensing applications. Optical fiber technology has changed the world in ...
