The microscope adopts a newly designed infinity-corrected optical system and professional infinity long working distance plan achromatic metallurgical objectives, providing comprehensive observation modes including bright field, dark field, simple polarized light, and differential interference contrast (DIC). It meets various research and inspection requirements and is widely used in casting, metallurgy, heat treatment, printed circuit boards (PCB), semiconductor research, raw material inspection, and material analysis applications.

Inverted Metallurgical Microscope for Material Analysis

Model:TD-4XC

I. Product Introduction

The Inverted Metallurgical Microscope is designed for direct observation and analysis of the microstructure of metallic materials, including material defects, segregation, primary carbides, decarburized layers, coating thickness, oxide film thickness, nitrided layers, and microstructures formed under various conditions such as welding, cold working, casting, forging, and heat treatment. It helps evaluate material quality and performance through microscopic examination.

The system requires proper specimen preparation before observation. The complete image analysis system consists of a metallurgical microscope, camera, computer, printer, and professional image analysis software, forming an integrated optical imaging and analysis system.
