L3230BD upright bight or dark transmitted or reflected metallurgical microscope is a kind of multifunction industry inspecting microscope. It is equipped with bright or dark field objectives, wide field eyepieces and integrated polarization observation device, the Kohler illuminator is used in the transmitted and reflected illuminating system, the whole field is clear and uniformity. It is suitable for inspecting, such as semiconductor silicon wafer, LCD floor plate, electrocircuit plate, solid powder and all kind of industry sample that translucent or opaque. It is the ideal instruments in research work in biology, metallography, mineralogy, precision engineering, electronics, etc.

	Features:
	▲ Adopt UIS optical system and modularization function design. ▲ Long W.D bright or dark field plan objectives (no cover glass), the field is wide and clear. ▲ Wide-field plan eyepieces: field number Ф22mm. ▲ Coaxial coarse/fine focus system, with tensional adjustable and up stop, minimum division of fine focusing: 2μm. ▲ Maximal movement of stage is about 30mm. ▲ Integrated polarization observation device, the polarizer can be circumrotated for 360°. ▲ The reflecting illuminator is 12V 50W halogen lamp and the lamp box cover can be revolved, replacing lamp facility and safety. The transmitted illuminator is 12V 30W halogen lamp and adding radiator. ▲ Trinocular can be observation for eyepieces and microphotography in 100% light flux, suits for dark field microphotography.
