  • Optical Plastic refractive measurements in the visible and the near infrared regions
    Applied Optics, 2000
    Co-Authors: Iva D Nikolov, Christo Ivanov
    Abstract:

    Some new refractometric results are obtained in the visible and the near-infrared spectral regions. The main Optical Plastics are analyzed: poly(methyl methacrylate), polystyrene, polycarbonate, and styrene acrylonitrile. New materials, such as methyl methacrylate styrene copolmer, CTE-Richardson, Zeonex, Optorez, and Bayer are examined. The refractive indices are measured for wavelengths from 435.8 to 1052 nm with a new device. Abbe constants and dispersion coefficients are calculated. The measured and computed data is intended for designers and technologists.

  • surface integrity demands of high precision Optical molds and realization by a new process chain
    Procedia Engineering, 2011
    Co-Authors: E Brinksmeier, R Glaebe, J Osmer
    Abstract:

    Abstract For the replication of Optical Plastic or glass components molding inserts with specific functional surface and sub-surface requirements are needed to withstand the thermal and mechanical loads during the replication process and to ensure the desired Optical part quality with a surface roughness in the nanometer and a form accuracy in the sub-micron range. The conventional process chain for the manufacture of these molding inserts with a combination of grinding and polishing has severe disadvantages concerning machining time and production costs. Therefore, this paper presents a process chain consisting of a thermo-chemical surface treatment and a sub-sequent diamond cutting process for the manufacturing of Optical molding inserts.
