Ghaidaa Jabbar Habi

Abstract

This study implements the optical characteristics of Poly-Methyl methacrylate (PMMA) polymer before and after doping different percentages of Lithium Fluoride (LiF). Where the specimens were formulated as disk shape with diameter of (2.5 cm) and thickness of (0.148 cm) using Thermal pressing technology. The absorbance and reflectivity spectra were recorded in addition to their coefficients at range (300-1100) nm. Also, the study has included the determination of refraction and real and imaginary part of dielectric constant coefficients.

Keywords

Poly-Methyl Methacrylate (PMMA) Polymer, Lithium Fluoride (LiF), Refractive Index, Real and Imaginary Parts of Dielectric Constant.
