Instrument Introduction:

The most advanced level of technological development
Since 1979, Dr. Kernchen has been renowned for producing high-precision (1× 10-6 nD) automatic refractive indices with outstanding manufacturing performance.
In 2007, adhering to the tradition of precision manufacturing in Germany and years of strategic partnership with Anton Paar, Dr. Kernchen officially joined
Anton Paar Group has officially changed its name to Anton Paar OptoTec. After joining, Anton Paar Opto Tec will integrate with Anton Paar
The comprehensive advantages of the group provide customers with more advanced products and higher quality services.
