  • Superpulse Lasers - Definition and Applications
    Article - 14 Mar 2014
    Superpulse is a specific waveform commonly used in CO2 laser systems either in a pulsed or continuous pattern. Superpulsed lasers are capable of emitting several thousand bursts of power per second.
  • Radiance - Deinition and Introduction
    Article - 14 Mar 2014
    Radiance of a source is the power that is radiated from a surface within a solid angle and passing through a cross-sectional area. Radiance may be described as the power traversing at a point in a...
  • An Introduction to Bandwidth-Distance Product
    Article - 12 Mar 2014
    Bandwidth-Distance Product is a term used to describe the transmission of light through fiber optic cables. Data transmission through fiber optic cables is limited by attenuation and dispersion.
  • Beam Profiler - Definition and Applications
    Article - 12 Mar 2014
    Measurement of the optical beam profile is of critical importance in a number of laser applications.
  • An Introduction to Attenuation
    Article - 27 Feb 2014
    Attenuation is defined as the gradual loss in the intensity of any kind of flux when it passes through a medium.
  • Toric Lens - Definition and Applications
    Article - 6 Feb 2014
    Toric lens is a special type of lens having two different focal length and optical power in orientations that are perpendicular to each other.
  • Telecentric Lenses and Their Application
    Article - 6 Feb 2014
    Telecentric lens is a compound lens used in imaging systems to make objects appear to be the same size independent of their location in space.
  • Sagnac Interferometer - Definition and Applications
    Article - 4 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...
  • Radiometer - Definitions and Applications
    Article - 20 Jan 2014
    A radiometer is an instrument for detecting and measuring radiant flux/power of electromagnetic radiation. The term radiometer usually refers to an infrared radiation detector; however, it also refers...
  • Diopter (unit) - Definition and Applications
    Article - 28 Dec 2013
    Diopter is the unit of measurement of the optical power of lens or a curved mirror. In terms of numerical value, it is equal to the reciprocal of the focal length of a lens of curved mirror measured...
