Trinocular Metallurgical Microscope (MM-4)

The MM-4 Trinocular Metallurgical Microscope is designed for advanced reflected light examination of metallic and opaque specimens. It features a robust mechanical body with a trinocular observation head, precision ball bearing nosepiece, and graduated mechanical stage. Bright halogen illumination with solid-state power control, semi-plan achromatic optics, and precise focusing mechanisms support detailed surface structure analysis in metallurgical, material science, and industrial laboratories.

Working Principle

 

The MM-4 Metallurgical Microscope operates by directing bright field reflected light from a halogen source onto the surface of opaque samples. The reflected light is captured by semi-plan achromatic objectives and transmitted through the trinocular optical system. Adjustable illumination, precision focusing, and controlled stage movement allow accurate observation of surface structures, grain boundaries, and material features under stable laboratory conditions.
