Overview
The BMM-88 series research-oriented upright metallographic microscope is suitable for microscopic observation of opaque objects. This instrument is equipped with a large moving range stage, a falling beam illumination device, a flat field achromatic objective lens, and a large field eyepiece, with clear images and good contrast. It is also equipped with a polarizing device, making it an ideal instrument for research in metallurgy, mineralogy, precision engineering, electronics, and other fields. It is particularly suitable for observing metal structures in the copper, aluminum, and steel industries. It is also suitable for use in schools, scientific research, factories and other departments.

It is particularly suitable for observing metal structures in the copper, aluminum, and steel industries. It is also suitable for use in schools, scientific research, factories and other departments.
2、 System Introduction
This system combines traditional optical microscopes with computers (digital cameras) through photoelectric conversion. It can not only perform microscopic observations on the eyepiece, but also observe real-time dynamic images on the computer (digital camera) display screen, and edit, save, and print the required images.
