Abstract

This research paper illustrates the simple and effective method for the fabrication of Poly(dimethylesiloxane) PDMS spherical convex micro-lens array. The research is consist of two main fundamental processes i.e. fabrication of micro-lens array mould cavity (master-mould) using micro-EDM and development of PDMS micro-lens array using micro-molding technique. Firstly a master mould array containing 25 concave hemispherical profiles using Micro-EDM process of diameter 190 micrometers and depth of 95 micrometers is fabricated. In second stage a 5 X 5 array of micro-lens of PDMS material is developed using the above machined master mould by micro-molding technique. Scanning electron microscopy (SEM) and optical observations confirms that the fabricated PDMS arrays are produced without defects and good surface finish. This method of fabrication is simple, productive and cost effective. Only the problem is control over the bubbles generation during curing of PDMS.
