Kalnew Precision Refractometer KPR-300
With the V-block method, samples finished to a 90 degree angle are measured. The instrument is capable of high-accuracy measurements (in comparison to the Abbe method (critical angle method)), with a measurement accuracy of ±4 × 10-5, and a display resolution of 0.1 × 10-5. The finished surface of the sample does not require the finished accuracy of general spectrometer prisms, and a grinding finish is enough (polishing the surface is not required), so sample preparation is not time consuming. The instrument can also measure small lenses with several millimeters in diameter, used in in-vehicle cameras and smartphones.
