RESUMO

The purpose of this work was the development and production of acrylic biconvex lens by injection process to be used in optical and science teaching at elementary and high schools. The importance of such work is based in the deficiency of experimental didactic material made in Brazil. In order to achieve the intended objective it was necessary to study the thermoplastic injection process and adapt it to the fabrication of an optical element. During the development of the work a mold was designed and constructed in according to technical specifications and based on results of numerical simulations. After the injection tests the lens were characterized by theirs optical parameters: transparency, birefringence, refraction index, focal distance, curvature radius and MFT
