Using a state-of-the-art laser-assisted diamond-machining system, ULO Optics and LBP Optics are developing a unique class of lenses to fine-tune the laser-cutting process for industrial steels Laser ...

Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused ...

To demonstrate confocal imaging, the scientists used a bench-top mockup of the objective lens with an integrated 3-D MEMS mirror. Liu et al. attached the mirror onto the sample stage using a ...

(Nanowerk Spotlight) Conventional lenses made of glass can only focus light in a limited way, restricting many potential applications in optics and photonics. Now researchers have developed a new type ...

Smaller and more versatile laser confocal microscopy platforms would potentially be of great value for in vivo imaging of live biological specimens, in scenarios where the size of conventional ...

Tunability in lenses typically requires bulky components, but researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied.
