| Abstract [eng] |
The main aim of the project is to design the periodical microstructure with the theoretical calculation by executing and analysing the Red, Green, and Blue laser of wavelength λ=0.633nm, λ=0.532nm, λ=0.441nm of period, 4μm, 5.6μm, 10μm with the highest depth for the respective periods thus giving the highest Diffraction Efficiency for the 1st order maxima. The results are further compared and analysed further, after the theoretical calculation the periodical microstructure is manufactured by Contact lithography, Ion etching, UV Replication, and Electroplating process to produce the Nickel structure, this Ni structure is analysed with the help of Atomic microscopic producing 2D, 3D and the profile is generated. The fabricated Ni structure is thermal replicated on the Polycarbonate surface with many Imprints on it. From the analysis, we see there are two defects that occur while manufacturing the periodical microstructure and measurement defect that happens during the analysis in Atomic force microscopy for the Red laser. |
