  • Shape and Refractive Index Recovery from Single-View Polarisation Images
    In this paper, we propose an approach to the problem of. simultaneous shape and refractive index recovery from multispectral. polarisation imagery captured from a single viewpoint. The focus of this paper is on dielectric surfaces which. diffusely polarise light transmitted from the dielectric body
  • Precision Refractive Zoom Lens with Long Focal Length (.pdf)
    allowed us to adjust critical. parameters “on the fly” as tolerances of glass properties and mechanical components were stretched to measurement lim-. its. The refractive zoom lens has 36 glass surfaces, and all of the measurements of refractive index, radius of curvature,. and glass thickness were
  • High Spatial Resolution Measurement of Volume Holographic Gratings
    ). where  λb  is the measurement  wavelength, n is the refractive index of the grating element (at the measurement. wavelength), Λ is the grating spacing, φ is the grating tilt angle, and θb is the angle of incidence measured inside the. media. From energy conservation, and assuming a perfectly
  • Gloss Standards and Measurement
    ) and sensitivity of the receptor are all specified and held constant within a given instrument. The theoretical standard for comparison is a highly polished black glass with a refractive index of 1.567, which is assigned a gloss value of 100 for each geometry. Several practical standards have been proposed
  • Zeta Potential Measurement (Aqueous and Non-Aqueous, Iso-Electric Point Determinations)
    limit of Dynamic Light Scattering depends upon the excess scattered light the sample generates compared to the suspending medium. Many factors will contribute to this lower size limit including the sample concentration, the relative refractive index (i.e. the particle refractive index compared
  • Measurement of Pigments with Dry Jet Dispersion Technology (.pdf)
    using the Mie theory. This means that you need to know. the refractive index (both real and imaginary parts). The imaginary part represents the degree of absorbance of a sample at a certain. wavelength. The imaginary part is different for each color pigment and is very. important
  • Medical Device Link .
    to refractive index is a function of the gold thickness. Under certain conditions, it may be tuned to give higher sensitivity than the corresponding intensity domain measurement. Whether an SPR system uses intensity or phase for making measurements, the outcome is a label-free measurement of the binding
  • MICRO: 'Round the Circuit
    the resolution to 65 nm for traditional lithography at the 193-nm wavelength. The technique also holds the potential to achieve 45-nm resolution at the 157-nm wavelength. One key to the successful use of the technique is a favorable refractive index. NIST points out that the refractive index of water
