Metallographic microscope is developed for the needs of semiconductor industry, silicon wafer manufacturing industry, electronic information industry and metallurgical industry. As a metallographic microscope user, he can experience its super performance when using it, It can be widely used in semiconductor, FPD, circuit packaging, circuit substrate, material, casting / metal / ceramic parts, precision mold testing. The instrument adopts two lighting forms of reflection and transmission. Under the reflected light illumination, it can observe the bright and dark field, DIC and polarized light. Under the transmitted light, it can observe the bright field. The stable and high-quality optical system makes the imaging clearer, Better lining. Ergonomic design makes you feel comfortable and relaxed at work

The illumination mode of metallographic microscope can be divided into two kinds: open field illumination and dark field illumination. The light is directed vertically to the surface of the sample to obtain an image with black image on the shiny back. Both types of illuminators can be used for open field illumination. When the light is illuminated in the open field, the objective lens is used as the light collecting lens to gather the light and shoot it to the surface of the sample, Then the light reflected from the surface of the sample enters the objective lens again to enlarge the object image. Therefore, the light twice passes through the light field of the objective lens and is divided into direct light illumination and oblique light illumination according to the lighting form. Direct light illumination is that the light source center is aligned with the sample, and the light rays are perpendicular to the surface of the sample, so the image is clear and flat. Oblique light illumination is to properly reduce the aperture light bar, It can improve the contrast of image, and it is more three-dimensional when the surface is convex. Dark field illumination

Advantages of metallographic microscope:

It can improve image contrast, image quality and make image color natural and even;

The angle of incidence beam is very large, which makes the effective numerical aperture of objective lens increase,

The identification ability of objective lens is higher than that of open field

Application: used for qualitative identification of nonmetal and special phase

Main features of the instrument

Metallographic microscope is a high-tech product developed by combining advanced optical microscope technology, advanced photoelectric conversion technology and computer imaging technology.
