  1. How Big Is The Alpha Particle? Laser Spectroscopy Provides New Results With Record Precision 2/4/2021

    The size of the alpha particle, the nucleus of the helium atom, has been measured more accurately than ever before. Results now indicate a size 1.67824(83) femtometers, which is 4.8 times more precise than previous measurements.

  2. MKS Instruments And Edmund Optics® Partner To Provide Richardson Gratings™ High-Precision Optical Gratings 1/28/2021

    MKS Instruments has partnered with Edmund Optics® (EO) to provide global access to their Richardson Gratings™ high-precision ruled and holographic gratings. EO is now a global distributor of Richardson Gratings products and offers a large selection of gratings in-stock and ready to ship.

  3. White Turns Into (Extreme-)Ultraviolet 1/25/2021

    By employing a novel phase-matching scheme in four-wave mixing, they could compress the spectral width of the initial broadband light by more than hundred times. The detailed experimental and theoretical resultshave been published in Nature Photonics.

  4. Novel Sensor To Measure Aerosol And NO2 Simultaneously 1/5/2021

    Recently, Prof. GAO Xiaoming's group from the Anhui Institute of Optics and Fine Mechanics (AIOFM) of the Hefei Institutes of Physical Science (HFIPS) demonstrated how they designed and manufactured a photoacoustic spectroscopy based sensor to measure aerosols and nitrogen dioxide (NO2) simultaneously.

  5. Vibrational Encounters – Phonon Polaritons Meet Molecules 11/23/2020

    Researchers from CIC nanoGUNE BRTA (San Sebastian, Spain), in collaboration with the Donostia International Physics Center (San Sebastián, Spain) and the University of Oviedo (Spain) employed a spectroscopic nanoimaging technique to study how infrared nanolight - in form of phonon polaritons - and molecular vibrations interact with each other.

  6. Tohoku University Teaches Old Spectroscopy New Tricks 10/2/2020

    Tohoku University researchers have improved a method for probing semiconducting crystals with light to detect defects and impurities. The details of their 'omnidirectional photoluminescence (ODPL) spectroscopy' set-up were published in the journal Applied Physics Express, and could help improve the fabrication of materials for electric cars and solar cells.

  7. UniKLasers Targets Wide Range Of Applications With Launch Of Powerful Single Frequency Red Laser Series 7/14/2020

    UniKLasers Limited, a leading manufacturer of high precision scientific laser instrumentation, has launched a second-generation series of its Solo 640 range of laser equipment, offering greater precision and feature enhancement in areas reliant on single frequency laser technology such as high-resolution Holography, Interferometry, Raman and Brillouin Spectroscopy.

  8. Limitations Of Super-Resolution Microscopy Overcome 7/7/2020

    With high-resolution microscopy, it is theoretically possible to image cell structures with a resolution of a few nanometres. However, this has not yet been possible in practice.

  9. SWIR For Hot-End Glass Bottle Defect Inspection And Imaging 7/5/2019

    Manufacturers of glass hollowware have long sought a way to pick out defective product at the hot end of their process, while the pieces are still above 200ºC. At that glass inspection stage, rejects are identified, then shunted aside and reprocessed efficiently, greatly reducing scrap.

  10. NASA Piggybacks Spectrograph On Comm Satellite To Study Ionosphere's RF Disruption 1/9/2018

    The National Aeronautics and Space Administration (NASA) is set to launch its Global-scale Observations of the Limb and Disk (GOLD) mission to study Earth's near-space environment and better understand what disrupts radio signals and satellites used for communications and the Global Positioning System (GPS) for radio navigation.
