Whenever there is a boundary between two different surfaces, light is refracted because there is a change in the speed of light when it crosses from one material to another. The direction in which it ...

LAS VEGAS — Multiple companies used the American Academy of Ophthalmology annual meeting to introduce their versions of a new retinal imaging technology: spectral-domain optical coherence tomography, ...

Scientists have developed the first refractive lens that focuses extreme ultraviolet beams. Instead of using a glass lens, which is non-transparent in the extreme-ultraviolet region, the researchers ...

Optical coherence tomography (OCT) is the most promising imaging technique used in ophthalmology today. Noninvasive, noncontact and having quick image acquisition makes OCT a requirement in ...

Scientists from the Max Born Institute (MBI) have developed the first refractive lens that focuses extreme ultraviolet beams. Instead of using a glass lens, which is non-transparent in the ...
