Metallurgical microscope MJ22

MJ22 metallurgical microscope is a upright microscope and applies to the microscopic observation of non-transparent or transparent objects. This instrument is equipped with reflective illumination and transmitted illumination system, plan achromatic objectives in  long working distance , wide field eyepieces and built-in polarization observation device. With the features of high image sharpness, good contrast and easy operation, MJ22 is an ideal instrument for the research of biology, metallography, mineralogy, precision engineering and electronics. It is widely used in universities, research institutions, factories and other sections.


  • Equipped with plan achromatic long working distance objectives( (no cover glass) in wide and clear field.

  • Coaxial coarse/fine focus system, tensional adjustable, with adjustment limit stop, minimum graduation in fine movement: 2μm.

  • Equipped with two illumination system in epi-illumination and transmitted illumination, can do microscopic observation for non-transparent specimen and transparent specimen. 

  • 6V 20W halogen lamp, brightness adjustable.

  • Trinocular, can switch to normal observation or to polarization observation,  100% light passed for photography .
