4XB Metallographic Microscope

Introduction: 
 The 4XB binocular inverted metallographic microscope is used to identify and analyze the structure of various metals and alloy materials. It is suitable for microscopic observation of metallographic structure and surface morphology. It is an ideal instrument for metallography, mineralogy, and precision engineering research.

 

Observation system

The support area of the instrument base is large, and the bending arm is firm, so that the center of gravity of the instrument is low and stable and reliable. Because the eyepiece and the support surface are inclined at 45°, the observation is comfortable.

 

Mechanical stage

Mechanical moving stage, built-in rotatable round stage plate. There are two kinds of loading trays with the inner hole φ10mm and φ20mm.

 

Lighting system

It adopts Kohler lighting system, with variable light barrier and 6V20W halogen lamp lighting, with adjustable brightness. AC 220V (50Hz).
