New lens captures light invisible to eyes
The invisible light spectrum, encompassing ultraviolet and infrared wavelengths, has long beguiled the human eye. A revolutionary lens technology is now making this unseen light accessible, heralding ...
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. When sunlight hits ...
The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...
