  • Chromatic Aberration – The Definition of Chromatic Aberration
    Article - 2 Dec 2007
    Chromatic aberration is also referred to as color fringing. Chromatic aberration occurs when a lens system is creating different focal lengths for different wavelengths of light. In other words, it is...
  • What is Optical Aberration and Types of Optical Aberration?
    Article - 1 Dec 2007
    Optical aberration can be considered as a flaw or distortion in the image generated by an optical system such as a lens or mirror compared to the original image.
  • Dioptre - The Definition of Dioptre
    Article - 17 Nov 2007
    Dioptre is a measurement unit that describes the optical power of a lens or a curved mirror. Dioptre can be expressed as the reciprocal value of its focal length in meters.
