  • Jupiter's Comet Collision Sites As Seen in Visible and Ultraviolet Light
    This comparison of visible light (blue) and far-ultraviolet (FUV) images of Jupiter taken with the Wide Field Planetary Camera-2 (WFPC-2) on NASA'S Hubble Space Telescope show how the appearance of the planet and of comet Shoemaker-Levy-9 impact sites differ at these two wavelengths (1400-2100
  • Ultraviolet Curing
    Ultraviolet (UV) Curing is a process which utilizes light energy to increase the viscosity of a material after it has been applied to another surface. Generally, a liquid material is coated onto the surface and through a photopically driven chemical process. The process causes the liquid to undergo
  • Understanding Ultraviolet LED Applications and Precautions
    Ultraviolet light occurs between the visible and x-ray spectrums. The Ultraviolet wavelength range is specified as 10 nm to 400 nm; however, many optoelectronic companies also consider wavelengths as high as 430nm to be in the UV range. Ultraviolet light gets its name due to the "violet" color
  • Hubble Reveals Ultraviolet Galactic Ring
    similar to that of many other spirals. However, when the galaxy is viewed in ultraviolet light with NASA's Hubble
  • Computer Power User Article - Light My Fire
    fluorescent lamps have a different coating that filters most light wavelengths, producing only UV-A (an ultraviolet light that's less harmful than other UV wavelengths) and purplish light. Incandescent blacklights are just regular household bulbs with filters that emit only UV-A and a violet glow
  • Hubble Finds a Bare Black Hole Pouring Out Light
    Probing the heart of the active galaxy NGC 6251, NASA's Hubble Space Telescope has provided a never-before-seen view of a warped disk or ring of dust caught in a blazing torrent of ultraviolet light from a suspected massive black hole. This discovery, which is reported in the September 10 issue
  • UVC Lights Keep Hospital Cool, Efficient (.pdf)
    the most germicidal in the ultraviolet spectrum. Properly installed in air handlers, high-output UVC lights are designed to penetrate even the tiniest microbes to destroy their DNA and RNA, killing or deactivating them. In this manner, the lights effectively degrade mold and other organisms that sometimes
  • Key Benefits of Next-Gen UV-LED Tech
    Despite the potential hazards of ultraviolet light which are evident in everyday life, such as sunburn, the UV spectrum is proving to have many beneficial ?effects in a multitude of areas.
