The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...

Today at CES® 2026, L'Oréal Groupe, the world leader in beauty, introduced two breakthrough technologies that bring the power ...

The beauty giant unveiled new infrared light-powered hair and skin care devices Light Straight + Multi-styler and LED Face ...

Scientists have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems. Scientists from the University of Birmingham and the University of Cambridge ...

Infrared light passes through the metal lens and is converted into violet light and focussed in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.

As humans spend increasing amounts of time indoors, we lose access to the sun’s natural benefits. Recognition of season affective disorder has grown accordingly. While the actual occurrence of the ...
