Z-scan technique is used for the study of thermal lens effect. The refractive index change is observed due to photo thermal effect. For time constants the experimental values are about 10 times larger than the theoretical values which may be due to the assumption about the air-sample interface. The heat dissipation at the boundary of the sample is not considered. Due to the insulting effect of air it would take more time for the sample to reach thermal equilibrium.
Keywords: DB14/PMMA, Polymer, Refractive index, photo thermal.
