¡¡ Products -- Metallurgical Microscope -- L3203


L3203 reflected metallurgical microscope is applicable to observe the opaque objects. It is equipped with Epi-illumination system, infinity plan achromatic and long working distance objectives, wide-field eyepieces and integrated polarizing device. It provides clear and good contrast picture, beautiful sculpt, convenient operation. It is the ideal instruments for research work in metallography, mineralogy, precision engineering, electronics, etc. It is suitable for scientific research, teaching demonstration in the colleges and factory.


Adopt infinity optical system and modularization function design.
Infinity long W.D plan objectives , the field of view is widely and clear.
Wide-field plan eyepieces: field number §¶22mm.
Coaxial coarse/fine focus system, with tensional adjustable and up stop, minimum division of fine focusing: 2¦Ìm.
Integrated polarization observation device, the polarizer can be circumrotated for 360¡ã.
The Epi- illumination is 6V 30W halogen lamp and the lamp box cover can be revolved, replacing lamp facility and safety. 
Trinocular can be observation for eyepieces and microphotography in 100% light flux, suits for low illuminance microphotography.
