Is black a colour? Black isn’t in the rainbow, but where does it fit in the colour spectrum? What makes something appear ...

The AS7341 does not have the ability to split white light into a spectrum. There are 9 photodiodes in the sensor, which are more or less sensitive to different wavelengths.

The TT-OES9000 Optical Emission Spectrometer by Torontech combines smart design with advanced technology to deliver precision without complication. Its layout supports both high-volume labs and ...

What color is moonlight typically, and what other colors can moonlight look like from our perspective on Earth?

Sewage-contaminated water absorbs certain wavelengths of light, leaving a signature that can be detected by space-based instruments, a new study finds.

Color, as the way light's wavelength is perceived by the human eye, goes beyond a simple aesthetic element, containing important scientific information like a substance's composition or state.

The problem with purple is that it isn’t supposed to be possible to create a color from wavelengths on opposite ends of the spectrum. The shortest wavelength detection made by your S cones ...

Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the details, tho… ...

Spectrometer optics involves measuring light intensity by means of a specialized analytical tool called a spectrometer which separates light by wavelength. Spectrometers are used for a variety of ...

For thousands of years, humans were looking up at the star-studded night sky using just their eyes sensitive to the optical wavelength of the electromagnetic spectrum.The first telescopes ...

A spectrometer using double-layer disordered metasurfaces enables high-resolution (1 nm) wavelength measurement across 440–1,300 nm in a device smaller than 1 cm.
