Polarization Microscope Model NP-420

The polarization microscope NP-420 was developed for the research of crystalline structures and finds therefore a broad application scope in the geology, mineralogy and in the building material and glass materials science, also in the medicine, chemistry and the food research. The NP-420 is suitable with its good optical and mechanical quality - not least because of its robustness - in the best way for practice, research and training.
