Transparency and translucency

Transparency and Translucency

  • Transparency: Shining through, from Latin 'transparere' meaning be visible
  • Translucent: Shining through, from Latin 'translucere' meaning to shine
  • Opaque: Darkened, from Latin 'opacus'
  • Late Middle English: Influenced by the French form

Factors affecting transparency in polycrystalline materials

  • Crystalline grain size determines the size of grain boundaries
  • Reduction of particle size below visible light wavelength improves transparency
  • Microscopic pores near grain boundaries act as scattering centers
  • Porosity volume fraction needs to be reduced for high-quality optical transmission
  • Sol-gel chemistry and nanotechnology methods can achieve low porosity levels

Applications of transparency

  • Transparent materials used for dichroic filters
  • Optically transparent materials transmit most of the light and reflect little
  • Liquids and aqueous solutions are highly transparent
  • Absorption and scattering mechanisms determine the attenuation of light
  • Transparency used in various applications, such as windows in buildings and optical devices.

Transparent ceramics and their applications

  • Optical transparency in polycrystalline materials limited by light scattering
  • Light scattering depends on wavelength
  • Scattering centers have dimensions on a similar spatial scale as the wavelength of visible light
  • Primary scattering centers in polycrystalline materials: Pores and grain boundaries
  • Reduction of scattering center size below the wavelength of light leads to reduced scattering
  • Applications of transparent ceramics: High energy lasers, transparent armor windows, nose cones for heat seeking missiles, radiation detectors for non-destructive testing, medical imaging applications

Transparency in nature and related concepts

  • Transparency provides camouflage for animals in dimly-lit or turbid seawater
  • Many marine animals, such as jellyfish, are highly transparent
  • Transparency in nature is easier to achieve in specific environments
  • Diminished transparency in good illumination
  • Camouflage through transparency is effective for survival
  • Related concepts: Brillouin scattering, clarity meter, colloidal crystal, haze (optics), light scattering
