metallurgical microscope MJ33 in bright field & dark field is a microscope used in industrial inspection, equipped with bright/dark field objectives, wide field eyepiece and polarizing observation device. The reflective and transmitted illumination system adopts Kohler illumination with clear field of view. It can be used for the observation of semiconductor silicon wafer, LCD substrates, circuit boards, and other kinds of powder solid transparent or opaque industrial test specimen. This metallurgical microscope is an ideal instrument for research of biology, metallurgy, mineralogy, precision engineering and electronics engineering, etc.
Features of MJ33 metallurgical Microscope:
- Adopts infinity optical system and modularity function design.
- Long working distance bright/dark field plan objectives, wide and clear field of view.
- Wide field plan eyepiece: field number is 22mm.
- Coaxial coarse/fine focus system, tensional adjustable, with adjustment limit stop, minimum graduation in fine movement: 2μm.
- Built in switchable polarizer device, analyzer 360°rotatable.
- Reflected light source: 12V 50W halogen lamp, easy and safe to change lamp bulb.
- Transmitted light source: 12V 30W halogen lamp and heat sink.
- Trinocular can be switched visual observation to micro image shooting, can take 100% light transmitting photography.
