He replaced the concave lens with a second convex one. As a result, the light rays converge as they exit the eyepiece, creating a wider field of view, and one which is more evenly illuminated.

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...
