Paper Abstract

Here we present a refractometer for liquids based on a sinusoidal relief grating immersed in a small cuvette. He – Ne light is sent to the cuvette + grating device where it is diffracted. Zero, +1 and -1 orders appear. It is possible to calibrate the device by measuring +1 order intensity, when different liquids with known refractive index are poured in the cuvette. A theoretical study has been developed that supports the experimental results.
