MJ22 transmitted&reflected metallurgical microscope with plan achromatic objectives and wide field eyepieces can obtain clean image in the wide visual field. Polarizer device. can be  added in trinocular, MJ22 is broadly suitable to observe the surfaces of non-transparent object and trnsparent object, and widely applied in mine, colleges and scientific research department to observe internal configuration of material.

Features:
◆Coaxial coarse/fine focus system, with tensional adjustable and up stop, minimum division of fine focusing: 2μm.
◆Utilize reflected &transmitted light mix illumination; you can descry the special effect in some object.
◆6V 20W Halogen lamp, adjustable control.
◆Trinocular, can switch to observe normally or to observe the Polarize, can send 100% of light to the binocular eyepieces or to the top port.
