Abstract

"REFRATÈMETRO PORTáTIL PARA MEDIR O ìNDICE DE REFRAçãO DE UM LìQUIDO". é propiciado um refratómetro portátil que compreende: um cilindro de lente que possui um eixo geométrico do cilindro da lente; um prisma fixado a uma extremidade do cilindro da lente, o prisma tendo uma face de entrada que propicia uma superfície de fronteira entre o prisma e uma substância a ser medida; uma base óptica em formato de tubo dentro do cilindro da lente, suportada de modo giratório em torno de um eixo geométrico rotacional predeterminado perpendicular ao eixo geométrico do cilindro da lente; uma lente objetiva posicionada na base óptica, posicionada em relação à base óptica; uma escala óptica posicionada dentro da base óptica, no ponto focal da lente objetiva e meio de deslocamento que desloca a lente objetiva relativamente em relação à escala óptica em resposta a variações em temperatura pela rotação da base óptica em torno do eixo geométrico rotacional.
