The team has created a non-destructive approach that involves using a reflectance spectroscopy setup to obtain optical reflectance spectra of paper samples in the near-infrared, visible and near-ultraviolet wavelength ranges and centers on identifying and quantifying the concentration of chromophores-the culprit causing the yellowing within paper.
It involves using a reflectance spectroscopy setup to obtain optical reflectance spectra of paper samples in the near-infrared, visible, and near-ultraviolet wavelength ranges.
In this development, an increased light output was achieved due to the high-efficiency, low-loss design and modularization of the near-ultraviolet semiconductor laser used in the light source.
These include a recently revived near-infrared camera and the Advanced Camera for Surveys, which records both ultrasharp visible-light images and low-resolution spectra at visible light and near-ultraviolet wavelengths.
Sony Electronics introduces the XCD-SX900UV black-and-white, high-resolution digital CCD video camera with near-ultraviolet (UV) sensitivity.
The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.
The International Lunar Observatory Association has Memoranda of Understanding with China National Space Administration (CNSA) and the National Astronomical Observatories, Chinese Academy of Sciences (NAOC) to exchange observation time between China's Lunar near-Ultraviolet Telescope (LUT) aboard Chang'e-3 and the ILO-X Precursor and ILO-1 Moon South Pole missions currently in development for launch 2015-2016.
X-shooter is one of the most sensitive spectrographs on Earth and can observe light from the near-ultraviolet to the near-infrared in one shot.
