Built for detailed material-sample review, this High-Magnification Metallurgical Microscope with Autofocus is a capable High magnification metallographic microscope with Autofocus. It enables dual-view observation through binocular eyepieces and external display. USB-port compatible wireless-adapter supports wireless-data-transmission. Equipped with bright-field & dark-field modes and even coaxial-illumination, it reveals micro-defects such as grains, coatings and cracks sharply. It integrates image snapshot and measurement-analysis functions. Anti-vibration stable chassis ensures consistent imaging performance, while upgrade-ready modular layout lowers later-stage update costs.
4K camera integrated with trinocular metallurgical stand, realizing simultaneous eyepiece & screen viewing. Multi-output ports including HDMI, USB3.0 and WiFi for real-time ultra-HD micro-image capture.
Optical magnification 50-500 ×, maximum digital magnification 2000 ×. Precision optical-path with professional metallurgical objectives delivers sharp imaging of micro-metal textures and grain-structures.
Built-in auto-focus module enables fast, steady focusing without manual-operation, reduces image-shake and greatly boosts inspection-efficiency for uneven metallographic specimens.
One-piece cast-aluminum base keeps the unit well-balanced, free of wobble or shift during long-time slice-inspection and material-observation work.
Classic white-and-blue research-style body with standard trinocular metallurgical layout, clean and minimalist for laboratories and quality-inspection workshops.
Suitable for metal-metallographic analysis, semiconductor-wafer inspection, material-failure-analysis, university-teaching-research and component-quality-testing tasks.
Supports 4K (3840 × 2160) photo and video capture. Built-in on-monitor measurement and PC-software-based measurement available; dual-storage via USB flash-drive and computer. Supports depth-of-field stacking, image-stitching and secondary-development for convenient image-archiving, comparison and in-depth 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 needed for screen output.
4K ultra-high-definition imaging + Auto-focus: Native 4K resolution plus hardware auto-focus for uneven-surface specimens. Common metallurgical devices rely fully on manual focusing with lower image resolution.
Triple-output interfaces: HDMI + USB3.0 + WiFi wireless transmission. Traditional metallurgical devices usually only connect to PC without wireless-transmission function.
Dual-measurement modes: Offline built-in measurement on-monitor 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; data saving available with or without computer. Conventional models require PC for image-storage.
Advanced image-processing algorithm: Built-in depth-of-field stacking and image-stitching for uneven-height metallographic samples. General metallurgical microscopes lack such embedded algorithm-functions.
Secondary-development supported: Network-capable system enables automation-production-line integration. General metallurgical microscopes do not support secondary-development integration.
Dedicated metallurgical optical path: Optimized for metal-grain, coating and material-metallographic-analysis. Ordinary digital microscopes lack dedicated optical-path and cannot observe fine metallurgical-micro-structures.
Integrated with a native 3840 × 2160 4K image-sensor and calibrated with standard metallurgical-resolution-templates, the equipment achieves full-field uniform sharpness. It enables clear identification of microscopic features including metallic grain boundaries, plating delamination, surface micro-cracks and material metallurgical-tissues without peripheral defocusing.
Adopting high-quality achromatic metallurgical objectives for high-power microscopic-observation and analysis. The upgraded trinocular optical-tube realizes synchronous optical-viewing and digital-imaging, fully applicable to metallic-microstructure-research, coating-thickness-inspection, grain-quality-grading and industrial-quality-control scenarios.
The dedicated metallurgical-measurement-system provides real-time on-screen-parameter-overlay and multi-dimensional-data-analysis. It precisely measures critical metallurgical-parameters such as film-thickness, grain-dimension, fracture-width and stratification-gap, and supports instant annotation, specimen-image-storage and inspection-data-export. Compatible with depth-of-field stacking and image-stitching functions.
Dual-path transmitted-and-reflected-illumination guarantees qualified lighting for diverse-specimen-types. The precision XY-axis mechanical-stage delivers smooth-movement and rapid-target-positioning. The rigid full-metal-chassis provides excellent anti-vibration-performance, ensuring stable and reliable operation during prolonged professional-metallurgical-testing.
Semiconductor & Electronic Components: IC chips, silicon wafers, photolithography slices, PCB boards, FPC flexible boards, solder joints, pins. Inspection targets: Observe internal chip-circuits, wafer-coatings, cold-solder-defects, oxidation, circuit-scratches and pin-deformation; analyze micro-slice-structures under max 2000 × magnification.
Metal Materials & Metallographic Specimens: Metallographic slices, drill bits, milling cutters, stamped-metal hardware. Inspection targets: Metallographic-grain-structure-analysis, heat-treatment-material-identification; detect edge-chipping, micro-cracks, burrs and abrasion-depth.
LED Optoelectronic & Plastic-Molded Parts: LED chips, optical-plastic parts, injection & die-cut products. Inspection targets: Inspect tiny-notches, surface-stains, rough-edges, micro-foreign-particles, glue-delamination and sealing-micro-defects.
High-Precision Miniature Components: Connectors, terminals, micro-springs, tiny 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: Metallographic-slice-experiment-analysis, incoming-&-finished-goods sampling-inspection; photo-&-video-archiving for defective-evidence-records and export of formal-measurement QC reports.
Optical magnification ranges 50 ×-500 ×, max digital-magnification up to 2000 ×. Built-in auto-focus eliminates repeated manual-focusing for uneven-samples. Native 4K 3840 × 2160 resolution clearly captures metallographic-textures, wafer-coatings and micro-chip-traces, greatly boosting lab-inspection-efficiency for bulk-samples.
Triple-output ports: HDMI, USB3.0 and WiFi. HDMI connects-monitor for on-site-viewing; USB3.0 enables high-speed-PC- analysis; WiFi-wireless-casting to phones and tablets for cable-free-remote-observation, suitable for spot-sampling and group-teaching-discussion.
Two-measurement-solutions: built-in on-monitor-measurement and PC-software-based-measurement. Equipped with depth-of-field stacking and image-stitching to produce fully-focused-pictures of uneven-specimens and seamless-panoramic-views of large-samples. Supports secondary-development for production-line-integration, ideal for new-material-research and coating-tolerance-analysis.
Trinocular-synchronous-design allows simultaneous-viewing via binocular-eyepieces and 4K-monitor. Teachers and QC-inspectors can observe the same-micro-sample together, perfect for university-training and double-inspection of defects in factories.
Two-storage-options: direct USB flash-drive-saving for 4K-photos/videos, and PC-software-archiving for mass-images-&-measurement-data. Captured-records and dimension-reports can be exported and stored long-term, meeting traceability-demands of factory-QC, university-lab-reports and semiconductor-incoming-inspection.
