  • Measurement of Pigments with Dry Jet Dispersion Technology (.pdf)
    Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear colorful. Pigments generally are dry, fine powders that are practically soluble in many usual solvents. Pigments are used because of their color power. The first using of these compounds
  • Optical Glass Specifications
    indices of refraction. A high Abbe number generally gives less color dispersion and reduces color aberration. Also, certain glass types have different transmission wavelength regions.
  • Glass Material Specifications
    indices of refraction. A high Abbe number generally gives less color dispersion and reduces color aberration. Also, certain glass types have different transmission wavelength regions.
  • Manufacture of Sun Tan Creams and Lotions
    products can be either an oil-in-water or water-in-oil emulsion. These consist of emollients and lubricants, emulsifying and thickening agents, perfume, color, preservatives and UV filters and absorbers such as titanium dioxide or zinc oxide. Effective UV protection is dependant on completeness
