  • Brewster Window - Definition and Applications
    Article - 15 May 2014
    A Brewster window is an uncoated substrate that is positioned at Brewster’s angle within a laser, instead of external mirrors. This substrate acts as a polarizer such that the p-polarized light enters...
  • B-Integral - Definition and Significance
    Article - 15 May 2014
    B-Integral is defined as the measure of the non-linear phase shift of light in devices like amplifiers. B-Integral is a term that is specific to non-linear optics. The non-linear shift of the laser...
  • Photometer - Definition and References
    Article - 29 May 2014
    Photometer is an instrument for measuring the light intensity or optical properties of optical sources or detectors. It operates more like a transducer which converts electric current into mechanical...
  • Laser Mode Locking - Theory and Applications
    Article - 29 May 2014
    Mode locking is a technique used to obtain ultra short pulses from lasers. Lasers that are mode locked are capable of producing pulses having pulse widths in the order of sub-pico seconds or even...
  • Axicon Lenses and their Application
    Article - 19 Sep 2014
    The axicon lens is a specialized lens that bears a conical surface. The axicon lens images a point source as a line along the optic axis.
  • Aiming Beam and Coaxial Laser Beam
    Article - 19 Sep 2014
    An aiming beam is a laser beam (or any other light source) which is used as a light for guiding.
  • Bruker’s Contour Elite 3D Optical Microscopes
    Equipment
    Bruker has developed the Contour Elite™ 3D optical microscopes that integrate the ContourGT® platform’s metrology and Vision64® analysis software with high fidelity imaging capabilities.
  • Spectrograph - Definition and Use
    Article - 12 Feb 2014
    A spectrograph is a device that separates the incident light from an object into a frequency spectrum and measures the amount of radiation at each wavelength.
  • Sagnac Interferometer - Definition and Applications
    Article - 12 Feb 2014
    The Sagnac interferometer uses counter-propagating beams in a ring path. This is realized by either using multiple mirrors or with an optical fiber. Generally, three or more mirrors are used, so that...
  • What is Optical Resolution?
    Article - 30 Oct 2014
