Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision ...

From left to right: Schematic of the nonlinear optical mirror used for up-conversion imaging. Energy diagram showing the sum frequency generation process used for up-conversion. Representative ...

A project at the University of Science and Technology of China (USTC) has developed a contact lens allowing wearers to perceive near-IR wavelengths and see better in the dark. Described in Cell, the ...

In recent years, the world of optics has undergone a major shift. New research shows how light can be bent, focused, and even changed in color using structures so small they’re invisible to the eye.

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or “up-convert” the frequency of short infrared light to the visible range. Up-conversion of light has ...

Tired of using bulky night vision goggles for your clandestine nocturnal activities? An interdisciplinary team of Chinese neuroscientists and materials scientists has developed near-infrared contact ...
