R&D on new materials for modern technologies is being actively conducted in every industry. Many of these materials (especially polymer film and related materials) are of high refractive index-often too high for the existing Abbe refractometers. But these are now covered with the nD1.4700 to 1.8700 range of the NAR-4T.

 

ATAGO's Abbe Refractometers are widely used in a variety of fields; from basic research to product management.

Uses and Applications

For measuring the refractive index (nD) of liquid samples between 5 to 50˚C:
DR-A1, DR-A1-Plus, and NAR-1T LIQUID. We recommend the NAR-3T for high-accuracy measurements.
For measuring the refractive index (nD) of liquid samples up to 120˚C:
NAR-2T
For measuring the refractive index (nD) of solid samples (glass, plastics, films, etc.):
NAR-1T SOLID, DR-A1, and DR-A1-Plus. The NAR-3T is also capable of measuring clear, translucent glass or plastics.
For measuring liquid or solid samples with a high refractive index (1.47 to 1.87):
NAR-4T
For measuring and determining the refractive index or Abbe number of liquid or solid samples at different wavelengths:
DR-M Series: DR-M2, DR-M2/1550, DR-M4, and DR-M4/1550 (For high refractive index measurements.)
For determining average dispersion values or abbe numbers:
NAR-1T SOLID, NAR-2T, and NAR-3T
For measuring Brix (%):
DR-A1, DR-A1-Plus, and NAR-1T LIQUID. We recommend the NAR-3T for high-accuracy measurements.
For connecting to a printer:
DR-A1, DR-A1-Plus, and DR-M Series
For measuring birefringent (double refraction) samples (plastics, films) that have different refractive indices depending on their orientation, or for measuing the ordinary ray (n subscript null) or extraordinary ray (n subscript exponential) of liquid crystals (LCs):
DR-A1, DR-A1-Plus, NAR-1T SOLID, NAR-2T, NAR-4T, and DR-M Series
