  • Fivefactors to Consider When Choosing a Laser Diffraction Particle Size Analyzer (.pdf)
    Measuring particle size is an indispensable step in understanding a material's physical and chemical properties. Of the many particle sizing methods on the market, laser diffraction is one of the most popular because it's a fast, nondestructive technique that can analyze wet and dry samples
  • Choosing the Most Suitable Theory in Laser Diffraction Mie or Fraunhofer? (.pdf)
    Particle size analysis is based on the inversion of a diffusion matrix, the resolution of which is based on theories stemming from the equations of Maxwell. The Fraunhofer approximation and the Mie theory enable particle size distributions between several tens of nanometres and several thousands of
  • Laser Particle Size Measuring Instruments for the Determination of Particle Size Distributions
    Laser diffraction - for quick and dependable determination of the particle size. Areas of application cover practically all branches of industry. For example, laser diffraction can be found in the receiving, but also in the pre-delivery inspection of base materials, in which their particle size
  • Correction Methods for Semiconductor Laser Diodes
    A laser diode naturally produces a beam that is divergent, elliptical, and astigmatic. A variety of optical procedures are available to correct for these deficiencies, procedures that enable a laser diode module to produce a circular, diffraction-limited beam with very low divergence. * We can
  • Phase Conjugate Laser Optics - Preface
    mirrors can be implemented. inside a laser resonator as shown in Chapter 3. Besides the demonstration of high. brightness operation, the authors analyze in detail the stability and the mode. structures of these unconventional nonlinear resonators. To achieve high power. with a near-diffraction-limited
  • Two-photon microscopy with diffractive optical elements and spatial light modulators
    Two-photon microscopy is often performed at slow frame rates due to the need to serially scan all points in a field of view with a single laser beam. To overcome this problem, we have developed two optical methods that split and multiplex a laser beam across the sample.
  • Combining Size and Shape Analysis
    The fast size results provided by laser diffraction and the method's versatility in analyzing a wide range of. materials have made it the benchmark particle sizing technology for dry bulk materials. The particle size measurement is based on the diffraction of laser light by particles
