Metallographic microscope(ultra HD microscope) is a microscope that is suitable for observation of the surface of metal or non translucent object.
For our metallographic microscope GR3400, high quality of wide angle graphic can be observed by using the plan apochromat object lens or wide angle's eyepiece lens.
Use a 5 pins reverse revolver.
It also can be use for the quality control of mineralogy, precision machinery industry or even chemical industry etc..

  • Epi-illumination for polorized observation.
