摘要： Certain embodiments of the present invention provide a refractometer including: a housing having an immersion portion, the immersion portion having an opening; a light source for emitting a light; a light sensor for converting a received light into an electrical signal; a prism including faces, including: a first face proximal to the light source and the light sensor; a second face, at least a portion of the second face configured for contacting a sample liquid through the opening, and for forming an interface between the second face and the sample liquid; and a third face, wherein the light travels by: being directed towards the second face; being reflected at least in part by the interface towards the third face; and being reflected at least in part by the third face towards the light sensor. In an embodiment, the refractometer further includes a control portion for receiving the electrical signal, and for determining a refractive index of the sample liquid based at least in part on the electrical signal. In an embodiment, the control portion determines the refractive index in at least one of: a batch mode for detecting the electrical signal once; and a sequential mode for detecting the electrical signal at least twice. In an embodiment, the refractometer further includes a substrate at least partially positioned within the housing, the substrate supporting the light source and the light sensor. In an embodiment, the refractometer further includes a display portion connected to the control portion for displaying a representation of the refractive index.
