Abstract

POLARIZADORES DE RACIACION INFRARROJA SE CONSTRUYEN CON MATERIALES QUE PRESENTAN ALTA TRANSMITANCIA PARA EL ESPECTRO INFRARROJO Y ESPECIALMENTE PARA LA LONGITUD DE ONDA ESPECIFICA DEL LASER DE CO2. PARA LOS POLARIZADORES LINEALES EL TANTO POR CIENTO DE TRANSMISION LLEGA A SER UN 85 Y PARA LOS POLARIZADORES CIRCULARES DE UN 99%. LOS POLARIZADORES LINEALES SE BASAN EN EL EFECTO DICROICO QUE PRESENTAN LOS CRISTALES LIQUIDOS PARA LA RADIACION INFRARROJA RELACIONANDO EL PARAMETRO DE ORDEN Y LA RELACION DICROICA ENTRE LOS COMPONENTES DEL CAMPO ELECTRICO PARALELA Y PERPENDICULAR AL EJE OPTICO DEL CRISTAL LIQUIDO. LOS POLARIZADORES CIRCULARES CONSTITUIDOS BASICAMENTE POR LAMINAS DE ONDA QUE SON ORIENTADAS A 45'', CON EL EJE OPTICO RESPECTO DEL HAZ DE LUZ POLARIZADA LINEALMENTE Y QUE INCIDE POSTERIORMENTE SOBRE UNA PELICULA COLESTERICA TRANSMITIENDO LA LUZ POLARIZADA CIRCULARMENTE ADERECHAS Y REFLEJANDO LA LUZ POLARIZADA A IZQUIERDAS, COMPORTANDOSE COMO UN AISLADOR. OTROS MATERIALES UTILIZADOS SON: VIDRIO FLUORADO, SILVINA, FLUORITA Y SILICONA.
