For "Laser wavelength", the colors in the gradient and the dot does not match. For both "Laser wavelength" and "Grating line density", the range of the slider UI is not clear.

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

The toughest job a highbrow machinist can tackle is to make a diffraction grating. The end result does not look like much: just a piece of glass coated with a film of aluminum in which thousands of ...

Plug-in hybrid electric vehicles (PHEVs) have the most problems of any category of new vehicles, reports J.D. Power in the 2025 U.S. Initial Quality Study. That includes more problems than their ...

Entrepreneurs who build successful businesses often possess a unique ability to see what others don't—the critical bottlenecks hiding in plain sight that create frustration, inefficiency, and lost ...

A wide mode-hop-free and narrow-linewidth tunable laser diode source employing a Littman-Metcalf configuration with a diffraction grating is developed. We conducted a series of experiments to evaluate ...

In a physics first, a team including scientists from the National Institute of Standards and Technology (NIST) has created a way to make beams of neutrons travel in curves. These Airy beams (named for ...
