Gem Refractometer
FuZhou Auyat Optoelectronic Technology Co.,Ltd.
Gem tester refractive index is one of most important optical parameter. Gloss of gem can be estimated by the parameter. The kinds of gem can be precisely determined in accordance with the measured value of refractive index because every kind of gem has its inherent refractive. Besides, index of double refraction can be also measured. Through the parameter you can judge whether a gem is uniaxial or biaxial photopositive or photonegative. The gemological refractometer is characterized by small volume and less weight. It is easy to carry. It is a popular instrument used in jewelry market.

Refractometers
A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The refractive index of a certain sample varies for nearly all materials for different wavelengths. This dispersion relation is characteristic for every material. Temperature has a very important influence on the refractive index measurement. Therefore, the temperature of the prism & the temperature of the sample have to be controlled with high precision.

Optical Fiber Cable Testing Equipment
Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications Optical fibers are very strong, but the strength is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The initial fiber strength, as well as its change with time, must be considered relative to the stress imposed on the fiber during handling, cabling, and installation for a given set of environmental conditions. There are three basic scenarios that can lead to strength degradation and failure by inducing flaw growth: dynamic fatigue, static fatigues, and zero-stress aging.

Particle Size Analyzers
Particle systems can be complex, but measuring them doesn’t have to be! Anton Paar offers two different technologies to characterize particles from the nanometer to the millimeter range. The Litesizer series employs light-scattering technology to determine not only particle size, but also zeta potential, transmittance, molecular mass, and the refractive index of nano- and microparticles in liquid dispersions. The PSA series uses laser diffraction technology to measure the size of particles in both liquid dispersions and dry powders in the micro and millimeter range. Side by side they open up a wide range of possibilities for comprehensive particle characterization.

Application Specific LC System
Reducing Sugar Analysis System
The Nexera reducing sugar analysis system uses Shimadzu’s unique post-column boric acid-arginine fluorescence derivatization method. Unlike the refractive index detectors and evaporative light scattering detectors (ELSD) commonly used for sugar analysis, this system reduces the effects of impurities and offers both high sensitivity and a wide dynamic range. As a result, sugars contained in samples can be analyzed simultaneously, without dilution even when there are significant concentration differences.
