Desenvolvimento de um protótipo para medição de filtros polarizadores de óculos de sol de acordo com a NBR15111

Abstract

The use of polarizing filters in sunglasses is becoming very common worldwide. In Brazil, despite the NBR15111:2004 has specific requirements for its use (position and efficiency), there is no proper national equipment to perform the measurements needed for evaluation. This paper describes the development of a prototype capable to perform measurements on sunglasses in order to verify their suitability for this standard, which
