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

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 ...

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 ...
