It filters blue light and UV rays. The added cost depends on the lens material, but the Blokz lens coating can be added to non-prescription, single vision, bi-focal or progressive lenses ...

When a beam of infrared light strikes their ultra-thin lens—barely thicker than a red blood cell—it emerges on the other side ...

In recent years, the world of optics has undergone a major shift. New research shows how light can be bent, focused, and even ...

A couple of years ago, Light ... 16 lenses. Ten or more of them capture an image simultaneously but at different focal lengths and the camera then combines those separate images into a single ...

A team of physicists at ETH Zurich has created a tiny metalens that can half the wavelength of incident light. They have achieved this using a special metal-oxide lens material called lithium niobate ...

BK7 K9 Glass Plano Convex Optical Single Lens: Optical Lenses are optical components designed to focus or diverge light, widely applicated from microscopy to laser processing. A Plano-Convex or Double ...

“The lens of the eye, when we’re born, is this: it bends light rays and it’s nice and clear,” said Dr. Madhu Gorla, an ophthalmologist at Chicago Glaucoma Consultants. As we age, it gets ...

And in research labs, these lenses could reduce the complexity of nonlinear microscopes. With the ability to focus and shift light frequencies on a single thin surface, scientists could design ...
