Abstract:
A color measurement instrument is used as a shade card generator and printer. Spectral geometries of D/8, D/0, 45/0, 0/45, D(hemisphere)/8, D(hemisphere)/0 or others are applied. The light spectrum of the illumination source (2) lies in the range of 350 - 1100 nm. An integrating sphere (3) is used in the case of D/8 geometry. A detector (7.5) and an optical assembly (7.2, 7.3, 7.4) using a variable sample aperture are between the light source (2) and the sample.
Abstract:
A colour optical measurement instrument for colour formulations and defining the camouflage property of a sample is operating in the wavelength range of 350nm to 1100nm. The colour difference in the visible range and in near infrared range is quantified. The instrument is equipped with an illuminition source, an integrating sphere in case of D8 geometry, a detector with an optical assembly between the source and the sample. A variable sample aperture is provided for proper optical focussing.
