摘要： A portable refractometer is provided that includes a lens barrel having a lens barrel axis. A prism is secured to one end of the lens barrel, the prism having an entry face that provides a boundary surface between the prism and a substance to be measured. A tube shaped optical chassis is inside the lens barrel, and is rotatably supported about a predetermined rotational axis perpendicular to the lens barrel axis. An objective lens is arranged in the optical chassis, and is positioned in relation to the optical chassis. An optical scale is arranged inside the optical chassis, at the focal point of the objective lens. A mover moves the objective lens relatively in relation to the optical scale in response to changes in temperature by turning the optical chassis about the rotational axis.
