  • How Do Fluorescent Microscopes Work?
    Article - 23 Jan 2023
    Although transmitted light microscopy techniques, including differential interference contrast (DIC), phase contrast, and polarized microscopy, have improved the visualization of living specimens by...
  • How to Reduce Noise in Satellite Imaging
    Article - 21 Jan 2023
    Many satellite photos are distorted by noise, which lowers the visual quality and inevitably causes processing problems. To reduce this noise, a number of remedies have been put forth utilizing...
  • What is Photoelectron Spectroscopy?
    Article - 31 Oct 2022
    Photoelectron spectroscopy involves the detection of the kinetic energies of photoelectrons emitted following an ionization event. If it is assumed that the emitted photoelectrons do not undergo any...
  • What is Phase Contrast Microscopy?
    Article - 26 Oct 2022
    Phase contrast microscopy manipulates phase shifts in light as it passes through transparent specimens. By converting phase shifts to changes in amplitude (brightness), the method enables scientists...
  • What is Atomic Force Microscopy?
    Article - 25 Oct 2022
    Atomic force microscopy (AFM) was first demonstrated in 1985 by Binnig, Quate and Gerber. Since then, the high-resolution non-optical imaging technique has become a powerful tool for surface analysis.
  • Lightigo: Laser-Induced Breakdown Spectroscopy Equipment for Rapid Elemental Analysis
    Article - 11 Oct 2022
    AZoOptics speaks to Jan Novotný, one of the founding members of Lightigo, about the significance of laser-induced breakdown spectroscopy (LIBS) in the elemental analysis field. Discussing Lightigo's...
  • How Do Space Telescopes Work?
    Article - 22 Aug 2022
    US President Joe Biden unveiled the first images from the James Webb Space Telescope (JWST) in July 2022. The joint NASA, ESA, and CSA mission is building on the success of previous space telescopes –...
  • Investigating Nickel on Silicon Thin Films with X-Ray Diffraction
    Article - 26 Jul 2022
    Explore how x-ray diffraction can be used for investigating nickel on silicon thin films.
  • Recent Advancements in Laser Ablation of Polymers
    Article - 30 Jun 2022
    High-energy laser pulses can melt and vaporize polymers. Due to this capability, laser ablation is an ideal approach to texture polymer surfaces.
  • How a Laser Mode Sensor Will Probe Neutron Star Interiors
    Article - 22 Jun 2022
    A laser mode sensor development by gravitational-wave scientists at the University of Western Australia could be the key to probing beneath the surface of neutron stars. The breakthrough may help...
