In Qing dynasty China, artisans augmented decorative pieces by incorporating iridescent kingfisher feathers—a technique known as tian-tsui. Scientists at Northwestern University’s Center for ...

Abstract: We demonstrate an integrated spectrometer-on-a-chip composed of an echelle diffraction grating (EDG) and metal-semiconductor-metal (MSM) waveguide photodetector array based on ...

The Cary 7000 Universal Measurement Spectrophotometer (UMS) is an all-encompassing device used for reflection, transmission, and absorption measurements from the near IR range all the way to UV. With ...

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 ...

Even plants have their favorite colors. Photosynthesis requires light, but plants don’t use all the colors that make up white light. Use a spectroscope to explore the absorption and transmission of ...

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, though ...

What is UV-Vis spectroscopy? UV-Vis spectroscopy is an analytical technique that measures the amount of discrete wavelengths of UV or visible light that are absorbed by or transmitted through a sample ...
