Developed for material micro-inspection, this Metal Analysis Metallurgical Microscope with 4K Ultra HD is a high-performance Metal Analysis Metallurgical Microscope with 4K Ultra HD. Boasting premium infinity-corrected optics, it delivers crisp visuals for both transparent and opaque samples. Modular design supports flexible post-sale upgrades of bright-field and polarized-light functions. Reinforced anti-vibration chassis eliminates image offset under high magnification. User-friendly controls and spacious stage enable long-time continuous testing. Selectable combined modules cut whole-machine-replacement costs, ideal for professional industrial-inspection and metallurgical-analysis work.

4K camera integrated with trinocular metallurgical frame, enabling simultaneous eyepiece and screen viewing. Dual-output ports: HDMI & Gigabit-LAN for real-time ultra-clear micro-image capture.
Optical magnification 50-600 ×, max digital magnification 4560 × with four-speed objective-zoom. Precision optical-path captures tiny micro-details of semiconductors, powders and fiber specimens.
Thick cast-aluminum base guarantees balanced weight distribution, free of wobble or shift during long-duration slice-inspection and material-analysis.
Minimalist white-blue trinocular layout, professional lab aesthetic for research-laboratories and industrial quality-control workshops.
Well-suited for semiconductor-wafer testing, metal-metallographic analysis, powder-and-fiber observation, university-research and component-quality-testing.
Supports native 4K photo & video capture. Dual-measurement modes: built-in on-monitor measurement and PC-software-based measurement. Dual-storage: USB flash-drive local-storage + PC-software archiving. Depth-of-field stacking and image-stitching are available via PC-software; secondary-development-interface supported for convenient image-archiving, comparison and advanced-data-analysis.
Binocular viewing & synchronous electronic observation: Synchronized display between eyepiece and monitor. Ordinary metallurgical microscopes only support eyepiece-only viewing; extra camera accessories are required for screen output.
Native 4K ultra-high-definition imaging: Delivers 3840 × 2160 4K resolution. Most conventional metallurgical microscopes are limited to 1080P resolution.
Dual-output interfaces: HDMI + Gigabit-LAN network port. Traditional metallurgical devices mostly only have PC-USB connection, lacking network-transmission capability.
Dual-measurement modes: Offline built-in on-monitor measurement plus PC-software-based measurement. Ordinary metallurgical microscopes only support PC-side measurement without hardware-embedded measuring function.
Dual-storage modes: Offline USB-flash-drive storage and PC-software-storage; saving data with or without a host-PC. Conventional models require PC for image-storage.
Advanced image-processing functions on PC: Depth-of-field stacking and image-stitching functions are available through supporting PC-software. General metallurgical microscopes have no such algorithm-functions.
Secondary-development supported: Gigabit-LAN enables system-integration for automated-production-line deployment. General metallurgical microscopes cannot support secondary-development integration.
Modular expandable optical-path: Supports adding polarized-light and other observation-modules without replacing the whole unit. Ordinary digital microscopes lack dedicated metallurgical optical-path and cannot observe fine metallurgical-micro-structures.
Adopting a native 3840 × 2160 4K industrial imaging sensor and calibrated with national-standard metallurgical calibration slides, the device achieves high-fidelity restoration of microscopic morphologies such as metal grain structures, semiconductor-wafer micro-textures, powder-particle shapes and fiber-tissue characteristics. It realizes uniform full-field imaging definition without peripheral blur or signal attenuation.
Equipped with a four-stage objective variable-magnification system, the instrument covers a total magnification range of 380-4560 ×. It satisfies dual-application-requirements: low-power macroscopic full-view scanning and ultra-high-power microscopic-microstructure fine-analysis, fully applicable to university-scientific-research, material-analysis and industrial high-precision-quality-inspection.
The embedded professional metallurgical-measurement-module supports high-accuracy dimensional-computation and real-time graphical-annotation. It integrates one-click high-definition snapshot and long-time dynamic-video-recording functions. All inspection-data and image-files support export and permanent-archiving, providing valid-data-support for academic- experimental-reports and industrial-quality-traceability-systems.
The professional trinocular optical-tube realizes synchronous optical-eyepiece-observation and digital-display-imaging. The dual-path transmitted-and-reflected-illumination-system is compatible with opaque-metal-specimens, transparent-powder-fiber sliced-samples and semiconductor-wafer-materials. The precision XY-axis mechanical-moving-stage features ultra-smooth-transmission and high-positioning-accuracy, enabling efficient and precise-specimen-detection.
Semiconductor & Microelectronics: Silicon wafers, photolithography slices, IC chips, PCB boards, FPC flexible circuits. Inspection targets: Micro chip-circuits, coating-defects, wafer-flaws, cold-solder-defects, circuit-scratches and pin-deformation; observe micron-slice-structures under max 4560 × magnification.
Metallographic Metal Specimens: Metallographic slices, steel-alloys, drill bits, milling cutters, precision-stamped-hardware. Inspection targets: Metallographic-grain-structure-analysis, heat-treatment-material-identification; detect edge-chipping, micro-cracks, burrs and abrasion-depth.
Lab Samples: Powder & Fiber: Metal-powder, chemical-powder, carbon-fiber, textile-fiber, thin-film-materials. Inspection targets: Observe particle-morphology, fiber-texture, film-delamination and micro-material-structures.
Optoelectronic & Precision-Plastic Parts: LED chips, optical-lenses, injection-molded-parts, sealing-glue. Inspection targets: Detect micro-pores, surface-stains, rough-edges, glue-bubbles & tiny cosmetic-defects.
High-Precision Miniature Components: Connectors, terminals, micro-springs, miniature-stamped-workpieces. Inspection targets: Observe tiny-gaps and crimp-flatness; perform pixel-level precise-measurement of length, hole-diameter and pitch.
Laboratory & Industrial QC Archiving: Material-research-experiments, incoming-&-finished-goods sampling-inspection; photo-&-video-archiving for defective-evidence-records and export of formal-measurement QC reports.
Max 600 × optical magnification and up to 4560 × digital magnification with native 3840 × 2160 4K resolution. It clearly displays tiny-structures such as metal-grains, wafer-textures, ultra-thin-coatings and micro-cracks, ideal for high-standard-analysis of chips, new-materials and electroplated-parts.
Two-measurement-solutions: quick built-in on-monitor-measurement, high-precision professional-measurement via PC-software. Two-storage-methods: USB flash-drive local-saving and PC-batch-archiving for images & measurement-data.
Trinocular synchronous-optical-path enables simultaneous viewing via binocular-eyepieces and 4K-monitor. Multiple-operators can check the same-micro-sample together, perfect for university-material-teaching and QC-double-re-check and R&D-team-discussion to reduce misjudgment.
Professional metallurgical-stage with multiple-objectives fits metal-specimens, PCB-coatings, semiconductor-chips, mineral-slices and thin-film-materials. Coaxial coarse-and-fine manual-focusing with heavy-anti-vibration-body, stable for incoming-inspection, new-material-research and long-static-lab-analysis.
