  • Amorphous hydrogenated carbon film
    Patent number: 7381452
    Abstract: The present invention concerns an improved process for the deposition of amorphous hydrogenated carbon film, more specifically an improved low temperature, low power and low vacuum cathodic sputtering process. The invention also concerns the film produced by said process and articles containing an amorphous hydrogenated carbon film coating.
    Type: Grant
    Filed: May 8, 2002
    Date of Patent: June 3, 2008

  • Optical element with full complex modulation
    Publication number: 20040233504
    Abstract: The present invention is related to an optical element that carries out the full complex phase and amplitude modulation of light wave fronts. The phase modulation can be attained by changing the optical pathway (for example, by changing the thickness or introducing a relief upon the optical surface) and the amplitude modulation is carried out by blocking the light pathway, (for example, by reflecting, absorbing, attenuating, blocking, polarizing or changing the polarization of the light.
