As such, there is no need to specify a value for y since entering a value for x will force a value of y.
  • For H2SO4 (sulfuric acid) and HNO3 (nitric acid), x relates to the wt % of these substances in water. e.g. x=0.4 for H2SO4 means a 40% ratio of H2SO4 by weight in an aqueous solution. H2SO4 and HNO3 are available down to stratospheric temperatures. Variable-compound ternary H2SO4-HNO3-H2O solutions also are given  with H2SO4.

    Thin film stack model: reflectivity/transmissivity online calculation for light incident at an arbitrary angle on a thin film stack.
    The algorithm returns full reflected/transmitted field, power, and phase information for incident TE (perp) and TM (para) waves.
    There are up several sets of information to be entered:
      1 Incident angle, centre wavelength, wavelength sweep range, and number of points(max 20) to compute across the wavelength sweep range.
      2 Complex index of refraction of incident medium (n,k). For air, n=1 and k=0 is a good approximation.
      3 Thin film stack. Enter stack information using the following notation, where the top film is closest to the incident medium (see examples below):
      Fixed index on each layer: notation Fully dispersive calculation: notation
        thickness1, n1,k1
        thickness2, n2,k2
        thickness3, n3,k3
        thickness1, {}
        thickness2, n2,k2
        thickness3, {}

        Deposition materials currently available are: Ag,Al,Au,GaAs,Ni,SiO2,
        Si3N4        .

        NOTE: if '{}' chracters do not work on your system, use '( )' characters.
      4 Complex index of refraction of substrate (ns,ks): either enter a fixed value OR leave the ns,ks fields blank and choose a substrate material for a fully dispersive calculation.
        Here are some examples of thin film stacks. Feel free to cut and paste into the "3" box below. The first example uses fixed index layers, the second example shows how to enter materials

    Arbitrary reflection on complex material. Calculate the reflected amplitude coefficients and phase shifts for linearly polarized light at an arbitrary polarization azimuth angle, incident at an arbitrary angle on a material of arbitrary real or complex index of refraction. (Assuming incident medium index =1).
    In the inputs below:
    n and k are respectively the real and imaginary values of the index of refraction, theta_i is the incident angle measured from the normal, angular sweep range is the angular range, centered on theta_i, across which luxpop will perform angle calculations, num sweep points is the number of points that will be computed during the sweeping.
    (For the example given below, the default values below will allow the user to locate the approximate Brewster angle for BK7 in the visible.) The source code for this calculation can be found in the "source code" box at the top of this page.

    n: (real)     k: (complex)     theta_i: degrees    
    angular sweep range: degrees      num sweep points: (max 25)        

    Gaussian Beam Propagation

    Perform calculations on Gaussian beam transformation by a lens. Notes: a) for these calculations the beam waists do not necessarily need to be at the focus, b) results for negative focal length lens may be suspect. Positive focal length calculations are valid.
    Parameters:
    d1,d2 (in millimetres): distance from beam waist to lens; w1, w2 (microns): 1/e2 beam radii at the waist; f (millimetres): lens focal length; l (nm): wavelength.

    If you enter d1, w1, f and l, the algorithm will return d2 and w2; additionally, the algorithm will return wL, the 1/e2 beam radius (although wL is not at a waist) at the lens.

    Additional "sweeping" feature: if one sweep value is entered, Luxpop will perform 15 calculations within a range bounded by the sweep parameter.

                     d1: mm   w1: mm            f:  mm       l: nm            
          sweep:    mm        mm               mm          nm

    Return the Rayleigh range and far field divergence angle given an initial 1/e2 beam radius  at the waist , wo (mm), and a wavelength, l (nm).

    wo: mm        l:nm   

    Return the 1/e2 beam radius  (in mm) given a distance from the waist , z (mm), a beam radius at the waist, wo (mm), and a wavelength l (nm). Additional "sweeping" feature: if one sweep value is entered, Luxpop will perform 15 calculations within a range bounded by the sweep parameter.

    z:   mm     sweep: mm about nominal values
    wo:mm     sweep: mm about nominal values
    l:   nm     sweep: nm about nominal values       

    Conversions

    Convert between photon energy (in eV) , wavelength (nm in vacuum), frequency (Hz), and wavenumber (cm-1).
    If you enter a value in the energy field and leave the others blank, the algorithm will return the wavelength, frequency, and wave number for the given energy.
    If you enter a value in the wavelength field and leave the others blank, the algorithm will return the energy, frequency, and wave number for the given wavelength. oWww Bestforexsite Forex Forex Trading Course Which One Is Worth Studying Best Forex Site Welcome to Luxpop!
