Light dark field metallographic microscope CMM-90AZ

Detailed technical parameters of CMM-90AZ bright dark field metallographic microscope

1、 Instrument usage

Infinite bright and dark field of view transmission and reflection metallographic microscope is a multi-purpose industrial inspection optical instrument, equipped with bright/dark field objectives, large field eyepieces, and polarized observation devices. The transmission and reflection illumination adopts the "Kohler" illumination system, and the field of view is clear. It can be used for the inspection of semiconductor silicon chips, LCD substrates, circuit boards, solid powders, and various other transparent or opaque industrial samples. It is an ideal instrument for research in biology, metallurgy, mineralogy, precision engineering, electronic engineering, and other fields

2、 System Introduction

The infinite bright and dark field of view transmission reflection metallographic microscope 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.
