Inverted Bright/Dark Field Metallurgical Microscope OC-40BD
Stable inverted metallurgical microscope with bright & dark field for clear observation of microstructure, inclusions, coatings and defects.
The Inverted Bright/Dark Field Metallurgical Microscope OC-40BD uses an infinity‑corrected optical system and professional bright/dark field reflected illumination. Its inverted structure provides excellent stability and convenience for observing large, heavy, or tall mounted samples. It delivers high‑contrast, clear images for metal, alloy, PCB, semiconductor, composite and ceramic material analysis, widely used in quality control, material research, failure analysis and laboratory testing.
Key Selling Points
- Inverted structure ideal for large, heavy and tall mounted specimens
- Built‑in bright field & dark field observation for clear defect and inclusion detection
