LM-4XC Trinocular Inverted Metallurgical Microscope

Product Summary

The LM-4XC Trinocular Inverted Metallurgical Microscope is a professional industrial-grade metallurgical microscope built with an infinity corrected optical system, designed for high-precision microstructure observation and analysis of opaque materials. Featuring a stable inverted microscope structure and trinocular viewing head, it delivers sharp, distortion-free flat-field imaging performance and is widely deployed in manufacturing quality control, material research laboratories and educational institutions for routine metallographic inspection.

  • It performs quality verification of castings, metallographic structure analysis after heat treatment, and inspection of surface phenomena including cracks, coating thickness and decarburized layers. It is a reliable industrial inverted microscope for metal analysis, covering steel, non-ferrous metals, electronic components, ceramics and mineral samples, as well as petrographic research in geological fields.
  • Equipped with a standard C-mount interface, the trinocular microscope with camera port supports 70% visual observation and 30% synchronous digital image capture. Its reflected Kohler LED illumination system ensures uniform and comfortable viewing field, while the DC5V low-voltage power supply and ergonomic low-hand operation design guarantee safe, fatigue-free and efficient daily operation.
  • As an upgradeable digital inverted metallurgical inspection microscope, it is compatible with optional industrial CCD cameras and professional metallographic grading analysis software, enabling automatic grain size rating, inclusion detection and standardized test report output. It serves as an essential instrument for material science research, metallurgical production control and academic teaching.

 

Why Choose LM-4XC Trinocular Inverted Metallurgical Microscope
Obtain Excellent Image Quality Save Time on Metallographic Analysis User-Friendly & Low Operation Threshold Flexible Modular Upgrade Solution
Adopts LIOS infinity flat-field achromatic optical system and Kohler LED illumination with uniform brightness. It delivers sharp, low-distortion images at high magnification and ensures stable and repeatable metallographic testing results. Equipped with inverted optical design and large three-layer mechanical stage for heavy and bulky specimens. Easy sample placement reduces repeated focusing and greatly improves inspection efficiency. It features a 360° rotatable trinocular head and right-hand centralized controls. The ergonomic design relieves fatigue during long-time observation, and new operators can get started with simple training.

Standard universal C-mount fits mainstream industrial cameras.

It can be upgraded with metallographic analysis software to realize automatic measurement, grain grading and test report export.
