Improving the Properties of Lenses Made of PMMA Polymer

Abstract

In this research, a group of samples of a polymer to which silicon dioxide was added were prepared, with different concentrations, by the casting method. And then using a spectrophotometer to study the absorbance and then extract the refractive index and Abbe number in order to use this data in the zemax program and the Lou and Bernan model to find out which of these samples is the best through the MTF examination. It was found that the sample with a concentration of SiO2 3% is the best sample, as it gave the highest contrast among the rest of the samples.
