Abstract: A refractometer and a method for measuring refractive index is disclosed. The refractometer comprises a light source, a reflecting module, a lens module, an array sensor, and a processor, wherein the reflecting module is configured to receive optical beams from the light source, the reflecting module comprises a detection surface configured to totally reflect at least part of the optical beams; the lens module is configured to converge optical beams from the detection surface onto a focal plane of the lens module; and the array sensor is located on the focal plane of the lens module.
