China Bestscope BS-5070 Polarizing Microscope with Infinite Optional System

Introduction
The BS-5070 series polarizing microscopes are specifically designed for geology, minerals, metallurgy, university teaching laboratories and other sectors. They also can be used in chemical fiber industry, semiconductor industry and pharmaceutical inspection industry. BS-5070 polarizing microscope features a highly robust construction and first class optics designed to provide a long life and excellent quality images. BS-5070BTR and BS-5070TTR have transmitted and reflected illumination system, which give a much better effect and wider application. The microscopes can be used for Single polarization, othorgonal polarization and conoscopic observation. Digital camera can be used together with the microscope for image analysis. Accessories like Gypsum slide, Mica slide, Quartz wedge and Mechanical stage are available.
