Metallurgical microscope MJ31
Routine metallurgical microscope MJ31

MJ31 is a microscope suitable for observation of transparent and non transparent object, it has transmitted and reflected lighting system, both are takes use of cool LED lamp with less thermal after long time working, to offer better clarity. The epi-illumination is kohler lighting and internet set polarization components to achieve polarizing observation. Objectives are long working distance and compatible to glass slide has cover glass and sample without cover glass.What is more, it is flexible expand to dark-field observation if needed. The microscope is good to use for bio-science, metal industry, geology, electronics and etc.

Features

  • Infinite plan achromat optical system, total magnification 50X~1000X.

  • Light path 0%/100% for eyepiece and photographing.

  • White LED lighting for reflected illumination and transmitted illumination.

  • It is available with common polarization observation.


Area of application

It is mainly used in semiconductor, FPD, circuit board, metal materials, precision cutting tools and other manufacturing fields, suitable for teaching and research.
