Gemstone refractometers are available both as classic optical instruments and as electronic measurement devices with a digital display. [3] In marine aquarium keeping, a refractometer is used to measure the salinity and specific gravity of the water. In the automobile industry, a refractometer is used to measure the coolant concentration.

Refractometers are frequently used by grape growers and kiwifruit growers for Brix testing of sucrose levels in their fruit. Refractometry is also used in the gelatin industry. To convert the RI of a gelatin sol (reported in Brix) to a gelatin concentration, one need only multiply by eight-tenths (0.8). A sol with a 10.0 RI would therefore be 8 ...
Most digital laboratory refractometers, while much more accurate and versatile than their analog Abbe counterparts, are incapable of readings on solid samples. In the late 1990s, Abbe refractometers became available with the capability of measurements at wavelengths other than the standard 589 nanometers.
Version 8.0 (June 2019) is the successor of both Mountains 7.4 and SPIP 6.7 software packages ("SPIP" standing for "Scanning Probe Image Processor") after the acquisition by Digital Surf of the Danish company Image Metrology A/S, the editor of SPIP. [25] Version 8.0 also introduces the analysis of free form surfaces, called "Shells" in the ...
A traditional handheld refractometer is an analog instrument for measuring a liquid's refractive index. It works on the critical angle principle by which lenses and prisms project a shadow line onto a small glass reticle inside the instrument, which is then viewed by the user through a magnifying eyepiece.
