1. Introduction
BPM-620 portable metallographic microscope is convenient for on-site materials structure
identification of various metal and alloy which can not be identified by making samples. It can be
widely used in the plant metallographic Laboratories for the metal materials analysis, materials
processing identification and the metallographic structure analysis. It also can be used for jade,
porcelain, bronze surface tissue structure observation and analysis.
BPM-602 uses LED vertical illumination, it is portable, convenient to use and safety. Optional
magnetic base is available, convenient for observation of large pipes and equipments.
This illumination can be used continuously for forty hours after a charge, long working time, save
energy, temperature rise is small, there is not much heat, safe to use.
Digital cameras can be used with this microscope to facilitate the acquisition, preservation and
image analysis.

lens 1# into the lens holder 2#. When install the objective, users can remove the microscope base
16# and then screw it on. Then place the treated metallographic specimen in the microscope
base and adjust the focus knob to start observation, please turn on the power switch 12#,
brightness can be adjusted freely according to needs.
The instrument adopts DC 3.6V lighting power, LED lamp, compact structure, safe and
convenient.
