Description
BK-POL polarizing microscope is a professional laboratory instrument. This series of polarizing microscopes can be divided into three types according to the light source: transmission, reflection, and transflective. Among them, the transmission light source is used for thinner and easy-to-observe slices, the reflection light source can observe some opaque materials, and the transflective light source can be used for both. The objective lens can be matched according to your needs, and generally, all kinds of magnifications are covered in the standard configuration. According to the specifications of the head, it can be divided into binocular and trinocular. Binoculars can only be observed with the eyes, and images cannot be exported to the computer. Trinoculars can be connected to a digital camera, and there is a special operating software that can export images and measure, etc. Polarizing microscopes are mainly used to study so-called transparent and opaque anisotropic materials, including geology, biology, and medicine.
