  • Patent number: 6844973
    Abstract: A plane diffraction grating based on surface normal rotation according to the present invention is designed so that the profile of the grooves at a radial area is determined depending on a rotational position of the area about a rotational center defined as a foot of the rotational axis on the surface of the plane diffraction grating.

  • Patent number: 5740079
    Abstract: The colorimetric value at a specified temperature is determined by measuring the colorimetric value of a colored material sample at an arbitrary temperature using a color meter such as a spectrophotometer, colorimeter, or densitometer, and by correcting the measured colorimetric value on the basis of the change in colorimetric value with temperature, which change in colorimetric value is computed from the difference in colorimetric values observed for a single colored material sample at a minimum of two different temperatures. When a spectrophotometer is applied, the spectral reflectance or the spectral transmittance of the colored material sample is measured. On the other hand, spectral reflectance or spectral transmittance is measured in advance for a dye or pigment at a minimum of two different temperatures. The difference (.DELTA.K) of absorption coefficient (K), the difference (.DELTA.S) in the scattering coefficient (S), and the difference (.DELTA.

  • Patent number: 5363238
    Abstract: The present invention discloses diffraction gratings which do not generate any thermal strain and can perform extremely high-precision and high-efficiency diffraction nearly free from scattered beams. The diffraction gratings are built by allowing the chemically deposited film of silicon carbide whose crystal planes are strongly oriented to the (220) planes in terms of Miller indices to form on the substrate comprising sintered silicon carbide, polishing the surface of the deposited film to 5 .ANG. RMS or less, and directly etched laminar-type grating grooves on that surface by using ion-beam etching.

  • Patent number: 4850711
    Abstract: A linearly polarized light beam is applied to the surface of a film and is reflected therefrom. The beam is then split into three light beams by three or four optical flats. These light beams are applied to photoelectric conversion devices after passing through analyzers with fixed analyzing angles. The photoelectric conversion devices convert the beams into electric signals representing the intensities of these light beams. Two ellipsometric parameters .psi. and .DELTA. are calculated from these three electric signals.
