| Applications of Refractometers |
Spectroscopic |
The DSR is particularly useful for measuring the optical properties of materials when the relationship between refraction and color are important in such materials as polymers, glasses, electro optical devices. The index-spectral data could potentialy be used for 'fingerprinting ' the characteristics of products such as beverages, wine, perfumes, inks.... |

The
DSR is a new refractometer from Schmidt + Haensch featuring a patented
multiwavelength source and detector along with Peltier temperature
controlled sample holder. The
DSR is a microprocessor controlled, critical angle refractometer
for
measuring the optical density of a wide range of liquid media
from low to high viscosity, and independent of opacity and color.
The DSR can be programmed to make a series of index measurements
automatically with different settings of wavelength, temperature
and time interval. The spectroscopic data is aquired at the discrete
wavelengths of light sources in the instrument and the data can
be plotted and intepolated for the full spectral range.
