Metallurgical microscope MJ43
Scientific grade metallurgical microscope MJ43

MJ43 is a research level metallurgical microscope with reflected lighting and transmitted lighting. Multi-function lighting attachment and broad-spectrum LED light source allows the microscope expand to reflected fluorescence function. The microscope body and structure is equivalent to Olympus BX43 optimized optical performance, offering various observation method possibility of dark field and DIC. All features give the microscope system ability to achieve composite micro observation of semi-conductor, FPD, electronic board, precision metal parts, physical materials and related industry area. It’s an ideal instrument for university laboratory, education and scientific research purpose.

Light source

30W high power LED light source, brightness is continous adjustable. Broad-spectrum light from 400nm~740nm, besides white LED light, offers fluorescence lighting of excitation band blue and green. 


  • Equivalent quality of Olympus BX43 microscope body.

  • Flexible expand to observation method of epi-fluorescence, dark field and DIC.

  • 30W LED light source is high efficiency and environment friendly.

  • Semi-apochromatic Fluor EPI metallurgical objectives are ideal view metal specimen.

  • Turret accommodates maximum sextuple filter block cubes allows to add filter cubes by needs.

  • Transparent plate is convenience to hold powder specimen.


  • Acheive equivalent performance as Olympus BX microscope

  • Fluor EPI metallurgical offers high clarity view especially high zoom magnification of 500X and 1000X

  • Available with professional polarization observation

  • Up and down illuminating and transparent glass stage, works for both of reflected light object and transparent object.

  • Down light with light intensity control function, remembering each zoom times suitable lighting.

  • LED light source is less temeperature after long time working, instant on-off, safety for lab working.

  • Flexible expand to fluorescence function with UV light.


  • Industry and physical material analysis

  • Metal structure and feature indentify

  • Medical material reaseach and study

  • Geology study

  • Electronics components QC
