PDMS has become a frequently used material in the elaboration of optical components such as: variable focal length liquid lenses, optical waveguides, solid elastic lenses, etc. In this work we describe the elaboration of PDMS samples, and we present the physical and optical properties of the material when a variation on its synthesis parameters (mixture ratio of base: curing agent, curing temperature and curing time) is implemented during their elaboration. Tensile and compressive tests were carried out to obtain the corresponding stress-strain curves of the material, and UV-Vis spectroscopy was applied to obtain transmittance and absorbance curves of the samples. A variation of the refractive index of the samples was observed and homogeneity of the samples was studied with the Raman spectra obtained from the samples. Results of the characterization determined the appropriate synthesis parameters for the elaboration of a tunable refractive surface for potential applications in artificial vision.
聚二甲基硅氧烷（PDMS）已成为制造光学元件时常用的材料，这些光学元件包括：可变焦距液体透镜、光波导、固体弹性透镜等。在这项工作中，我们描述了PDMS样品的制备过程，并展示了在制备过程中改变其合成参数（基础剂与固化剂的混合比例、固化温度和固化时间）时该材料的物理和光学性质。进行了拉伸和压缩试验以获得该材料相应的应力-应变曲线，并应用紫外-可见光谱法获得样品的透射率和吸光度曲线。观察到样品折射率的变化，并利用从样品获得的拉曼光谱研究了样品的均匀性。表征结果确定了用于制造可调谐折射表面的合适合成参数，以便在人工视觉中潜在应用。
