The Leica semi-automatic digital upright polarizing microscope - Leica DM4 P has a simple structure and flexible operation. The 25mm large field of view displays a complete high-definition overview image, identifying the structure of interest. The objective turntable is equipped with 6 objectives and has different magnifications to obtain rich sample information.
A polarizing microscope is a good choice for studying crystal structure. Whether it's minerals, plastics, polymers, drugs, pharmaceuticals, fuels, or binders, this polarizer can make samples appear crystal clear and transparent, helping you observe the content of interest and complete your research or quality control tasks.
