  • Patent number: 11249018
    Abstract: This application relates to an optical refractometer. In one aspect, the optical refractometer includes a prism, a light source and a sensor. The prism includes a first surface to which light is incident, a second surface to which the incident light is refracted when it contacts a substance, and a third surface reflecting the light refracted at the second surface toward the first surface. The light source emits light onto the first surface of the prism to be refracted toward the second surface. The sensor receives the light reflected from the third surface and output from the first surface. The light projected from the light source travels an optical path that directs the light to pass through the first surface of the prism, refract on the second surface, reflect on the third surface, and emit and condense to the first surface.
