BestScope Bertrand Lens Polarizing Light Microscope With Halogen Lamp

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.

Features
Excellent Infinite Optical System.
Widely used in geology, Mineralogy, Fossil fuel exploration.
Single polarization, othorgonal polarization or conoscopic observation is available.
Transmitted and reflected illumination system of BS-5070BTR and BS-5070TTR offers a much better effect and wider application.

Application area
With the features of easy operation, complete functions and economy, it is an ideal instrument in geology, petroleum, coal, mineral, chemicals, semiconductor and pharmaceutical inspection fields. It is also widely used in academic demonstration and scientific research area.
