  • Shape and Refractive Index Recovery from Single-View Polarisation Images
    . Moreover,. to render the problem of simultaneous estimation of surface. orientation and index of refraction well-posed, we enforce. a generative model on the material dispersion equations for. the index of refraction. This generative model, together with. the Fresnel transmission ratio, permit the recovery
  • Optical Glass Specifications
    Selecting a glass material is important since different glass types have different characteristics. Edmund Optics offers a wide variety of glass types which can be selected on the basis of the following characteristics. The index of refraction and Abbe number of a glass are typically used

  • Subwavelength, Binary Lenses at Infrared Wavelengths
    We describe the nanofabrication of subwavelength, binary lenses in GaAs for operation in the infrared. Subwavelength surface relief structures create an artificial material with an effective index of refraction determined by the fill factor of the binary pattern and can be designed to yield
  • Understanding Ball Lenses
    The effective focal length of a ball lens is very simple to calculate (Figure 1) since there are only two variables: the ball lens diameter, D, and the index of refraction, n. The effective focal length is measured from the center of the lens. Therefore, the back focal length can also be easily
  • Medical Device Link .
    . By making the metal layer 30 -50 nanometers thick, the wave can emerge through the other side of the metal and interact with whatever material is present. SPR is a powerful tool for biosensors because the angle of the shadow is affected by minuscule changes in the index of refraction of material above
  • MICRO: Building Copperopolis II - Yang (May 2000)
    as well as their optical properties, such as index of refraction (n) and extinction coefficient (k). Because n and k values depend both on the electronic structure of a polymer and on its porosity, they can serve as good indicators for monitoring low-k polymer formation. One low-k ILD material is SiLK
  • Medical Device Link .
    ). Besides preventing or dealing with unwanted penetration, parylene users must make sure that the surface of the device is clean prior to coating. Otherwise, Wolgemuth says, surface contamination will be both visible and magnified due to parylene 's transparency and index of refraction. Parylene
