What is a Abbe refractometer?

The Abbe refractometer is a device that can measure the refractive index of a material by the critical angle method. The appearance is similar to a microscope, and it is measured visually by looking through the eyepieces. The refractive index of a sample can be determined by placing a small amount of a sample such as a liquid or solid on a prism and observing the bright and dark regions generated by the light emitted from the prism. It is an indispensable device for manufacturers of optical equipment because it can evaluate optical materials such as optical films and optical glass.

Application of Abbe refractometer

The Abbe refractometer can determine the index of refraction of a sample. It is possible to accurately measure samples in various states such as liquids, solids, and membranes. It is used by manufacturers and analysis companies because it is possible to evaluate the optical performance of films, glass, lenses, etc. by determining the refractive index of the sample. The principle of the refractometer is also used in the handheld sugar content meter. Since the sugar content meter can measure the sucrose concentration in the sample, the sweetness of vegetables and fruits can be evaluated.
