  • What is Transparency?
    Article - 19 Sep 2014
    In optics, transparency, also referred to as pellucidity or diaphaneity, is the physical property of allowing light to pass via the material without being scattered.
  • An Introduction to Spectrophotometers
    Article - 28 Aug 2024
    Spectrophotometers are vital for optical analysis, measuring light behavior in materials to enhance research in chemistry, physics, and biomedical sciences.
  • What is a Prism?
    Article - 12 Sep 2014
    A prism is a transparent geometric optical object with a minimum of two polished plane faces inclined relative to each other, from which light is reflected or through which light is refracted.
  • Michelson Interferometer - Definition and Applications
    Article - 6 May 2014
    Michelson interferometer is a tool to produce interference between two beams of light. It is the most common design for optical interferometry and was invented by Albert Abraham Michelson.
  • Cassegrain Telescope - Definition and Applications
    Article - 1 May 2014
    The Cassegrain telescope is an astronomical reflecting telescope in which the light is incident on a large concave paraboloid mirror and reflected onto a smaller convex hyperboloid mirror.
  • What is Optical Phase Conjugation?
    Article - 6 May 2014
    Optical phase conjugation is a non-linear optical process, which is capable of time reversing the scattering process and healing the distortions in the wave front.
  • What is a Metal Halide Lamp?
    Article - 8 Oct 2013
    Metal halide lamps or metal halide arc lamps consist of a high performance arc discharge tube housed in an elliptical reflector that focuses the output into a microscopic optical train. The arc tube...
  • What is an Optical Fiber Isolator?
    Article - 22 Oct 2014
    Optical isolators are optical elements which allow light to propagate in only one direction. The propagation of light in one single direction is required in order to prevent optical back scattering or...
  • What is a Photodiode?
    Article - 5 Jun 2013
    A photodiode can be described as a photo detector that is capable of converting incident light into voltage or current.
  • Nd:YLF Lasers (Neodymium-Doped Yttrium Lithium Fluoride)
    Article - 15 Aug 2013
    Neodymium-doped yttrium lithium fluoride is the most common lasing medium for diode-pumped and arc lamp-pumped solid-state lasers.
