Features of xjx-j1, j2: this product is portable upright metallurgical microscopes. They have built-in illuminators whose brightness is continually adjustable. The size of field diaphragm and aperture diaphragm are adjustable. Besides, they adopt specimen stages which can be moved vertically and horizontally. Their coaxial fine and coarse focusing structures can be fixed at any position. The optical systems are equipped with three object lenses and two kinds of field oculars which can achieve generally used magnification ratios. Therefore, these two products can be used for routine metallurgical observations for factories, mines, research institutions and schools. They are especially suitable for such situations as fine grains, powder sample observation, large volume metallurgical examination and large area silicon chip inspection etc.

Features of xjp-j100, j200: this product is extensively applied in colleges, enterprise laboratories for distinguishing and analyzing the organizations and structures of various metals and alloys and for the metallurgical structure research of heat-treated materials. They have sharp image and wide field of view. The man-machine design of entire instrument makes them suitable for long term operation.

Features of xjl-j03: this product is a medium scale metallurgical phase microscope. It has such advantages as small volume, light weight and easy to use etc. over large scale metallurgical phase microscopes. Meanwhile, it has such advantages as more attachments, broader function range and capable of performing  bright FOV,  dark FOV and polarized light observation etc. over small scale microscopes. It can  be used by medium or small factories for locale metallurgical phase analysis, study and photography, video recording and image analyzing.

Features of xjl-j02A: The optical system of this model adopts negative focal length （f=-33m). Meanwhile, both photographical ocular and the dual-eye observation system adopts plane field of view which has the advantages of flat and clear. This product has many functions including bright FOV, polarized light, projection, photo shooting and grain size ratio etc., therefore it can used for Metallography and Metallurgical experiments for research institute, factories and schools.

Features of xjz-j6 and xjz-j6A: these two types of products can be classified as medium-sized metallurgical phase microscope. jxjz-6 adopts reflective illumination, which enables users to carry out bright field, dark field and polarized observations and photo shooting. jxjz-6 can also provide bright field observation and photography under the transmitted light. It is also equipped with 6cm×9cm and 135 photographical attachments. jxjz-6, jxjz-6A upright transmitted and reflected metallurgical phase microscopes are robust and stable, which fully ensures perfect mechanical performance. They can be used for experiments and analysis on such aspects as metallurgical phase, lithic facies and crystals for factories, college and universities, research institutions and the  electronic industry.

Features of xjg-j05: The optical system of this large scale metallurgical microscope adopts negative ocular made with high-quality lanthanum optical glass. Meanwhile, it adopts ocular with flat and large FOV and double eye ocular observing system which has excellent image quality for observation and photography. It can be extensively applied to study the microscopic organization of metals and can perform observation, projection and photo shooting in bright field, dark field and polarized lights. It can be to conduct metallurgical studies including Metallography, Thermal Processing, Metal physics, steel making and casting process etc.
