  • Field Curvature Aberration – What is Field Curvature Aberration?
    Article - 7 Dec 2007
    In optical microscopy, field curvature is an optical aberration that most of the experienced microscopists are familiar with. Field curvature occurs when lenses that have curved surfaces are used.
  • Ultrafast Lasers Reveal Atoms Colliding
    News - 8 Jul 2007
    Using laser pulses that last just 70 femtoseconds (quadrillionths of a second), physicists have observed in greater detail than ever before what happens when atoms collide. The experiments at JILA,...
  • Glare - What is Glare and How Does it Occur?
    Article - 19 Nov 2007
    When there is an excessive contrast between the dark areas and bright areas in the direction of viewing, then glare can result. Simply, when there is too much light hitting the surface, this...
  • Super Stable Fiber-Optic Network
    News - 8 Jul 2007

  • Converting Light into Electricity: How Does a Photovoltaic Cell Work?
    Article - 6 Nov 2024
    A photovoltaic (PV) cell, or solar cell, is a non-mechanical device that directly converts sunlight into electricity through the photovoltaic effect, using semiconductors to generate electric current...
  • Highly Efficient Room-Temperature Nanometer-Scale Laser
    News - 8 Jul 2007
    Scientists at Yokohama National University in Japan have built a highly efficient room-temperature nanometer-scale laser that produces stable, continuous streams of near-infrared laser light. The...
  • Methods Employed to Polarize Light
    Article - 3 Nov 2007
    Light waves that vibrate in a single plane are referred to as polarized light, and the transformation of unpolarized light into polarized light is called polarization.
  • High Precision Optical Measuring Instruments
